Indium chloride is an inorganic compound with the chemical formula InCl3. Its common form is white to light yellow crystals or powder, which is prone to moisture absorption and water seepage. The anhydrous form has a layered structure, while hydrates (such as InCl ∝· 4H ₂ O) are colorless crystals. Trichloroindium is soluble in water, ethanol, and ether solvents. The aqueous solution is acidic and may decompose and release hydrogen chloride gas when heated. As a precursor, it is used to prepare indium based compound semiconductors (such as InP, InSb) and transparent conductive thin films (ITO). As a Lewis acid catalyst, it participates in Friedel Crafts alkylation and esterification reactions.

Indium Trichloride (InCl3), CAS number 22519-64-8, molecular weight 221.18, is a white crystalline powder at room temperature with strong deliquescence. It can sublime at temperatures above 600 ℃, is easily soluble in water, and undergoes hydrolysis to form tetrahydrate (InCl3 · 4H ₂ O) and pentahydrate. It is the basic raw material for synthesizing organic indium compounds, and also the key form of high-purity anhydrous indium chloride, which is known as the "irreplaceable core raw material of LED representing cutting-edge lighting technology".
From mobile phone screens to hospital nuclear medicine disciplines, from organic synthesis laboratories to photovoltaic power plants, from optical lenses to rocket engine coatings, trichloroindium permeates every corner of modern technology and human health with its unique chemical properties and irreplaceable functions. According to the 2026 market report, the theoretical supply of high-purity trichloroindium worldwide is about 730 tons, while the actual demand has reached 755 tons after strategic replenishment and loss correction, forming a clear supply-demand gap of about 3.4%. The average spot price has risen to a range of over 35% per kilogram. The strategic value of this' industrial vitamin 'is becoming increasingly prominent with the development of technology.
1. Semiconductor and Electronics Industry
1.1 LED core chip: an irreplaceable "light source code"
The most core and important use of high-purity anhydrous trichloroindium (purity ≥ 99.999%, i.e. 5N~6N level) is as a key precursor for the production of LED core chips. In the metal organic chemical vapor deposition (MOCVD) process, high-purity indium nitride (InN) is generated by reacting with ammonia gas or directly participating in the epitaxial growth of III nitride semiconductors, ultimately producing blue, green, and purple LED chips.
It can be said without exaggeration that without high-purity trichloroindium, there would be no LED lighting revolution today. BOE and other display panel giants have abandoned the single source mode in procurement and instead adopted a "3+1" supply architecture, locking in three core suppliers with purification capabilities of 5N or above. It is precisely because the purity of trichloroindium directly determines the luminous efficiency, lifespan, and color consistency of LED chips.
1.2 Indium phosphide (InP) semiconductor: the "heart" of 5G communication
It is the core raw material for synthesizing indium phosphide (InP) semiconductor materials.
InP has ultra-high electron mobility and direct bandgap characteristics, making it an ideal material for manufacturing high-speed optical communication chips, lasers, and microwave devices, directly supporting the manufacturing of 5G/800G optical modules and quantum dot lasers. Against the backdrop of the explosive increase in demand for low resistivity conductive layers in flexible display panels, the strategic position of InP based materials has been further elevated.
1.3 Indium Gallium Arsenide (InGaAs): The "Thousand Mile Eye" for Infrared Detection
Indium gallium arsenide (InGaAs) material prepared from indium chloride is a core material for infrared detectors and optical communication devices, widely used in high-end fields such as night vision devices, fiber optic communication receivers, and LiDAR.
1.4 ITO transparent conductive film: the "invisible protagonist" of the touch era
It is the main raw material for preparing indium tin oxide (ITO) thin films. ITO film accounts for about 70% of global indium consumption and is used for transparent electrodes in mobile phone touch screens (such as iPhone touch layers), OLED displays, LCD displays, and solar cells. From flat panel displays to photovoltaic glass coatings, ITO is everywhere, and the starting point of all of this is trichloroindium.
1.5 CIGS thin-film solar cells: the king of weak light
Copper indium gallium selenide (CIGS) thin film solar cells are widely used in building integrated photovoltaic (BIPV) curtain walls and spacecraft power supply systems due to their excellent low light performance, with a global production capacity exceeding 10GW. They are the core source of indium element in CIGS cells, and their quality directly affects the photovoltaic conversion efficiency of the cells. Currently, the efficiency of CIGS cells has exceeded 22%, and trichloroindium plays an indispensable role.
2. Nuclear Medicine and Clinical Diagnosis
When indium in trichloroindium is replaced by the radioactive isotope ¹¹³ ᵐ In (Indium-113m), it becomes an indispensable radioactive tracer in the field of nuclear medicine, playing a key role in various clinical diagnoses.
2.1 Blood volume measurement - the "precise ruler" after cardiac surgery
The latest research in 2026 shows that the use of radioactive trichloroindium(III) (¹¹³ ᵐ InCl3) to measure blood volume after cardiac surgery can directly reflect the dynamic changes in blood volume and has important clinical practical value.
The study measured the blood volume of 24 postoperative cardiac patients at three time periods (when they entered the intensive care unit, 8 hours after surgery, and 24 hours after surgery), and the measured blood volumes were (81 ± 11), (81 ± 9), and (82 ± 8) mL/kg, respectively. Blood volume is significantly positively correlated with pulmonary capillary wedge pressure (PCWP), cardiac output index (CI), and urine output (r=0.3700~0.5751, P<0.01), and the correlation coefficient with mixed venous oxygen saturation (SvO ₂) is as high as 0.7243~0.7856 (P<0.01). This method provides precise basis for postoperative fluid management of the heart.
2.2 Brain scanning and diagnosis of brain diseases
Indium-113m labeled diethylenetriaminepentaacetic acid (¹¹³ ᵐ In DTPA) is a classic brain scanning imaging agent. Under normal circumstances, radioactive drugs are not easily able to penetrate the blood-brain barrier; When there are tumors, cerebral hemorrhage, cerebral contusion and other lesions in the skull that cause damage to the blood-brain barrier, radioactive drugs can concentrate in the affected area, presenting a "concentrated area" on the scanned image, thereby accurately locating diseases such as brain tumors, cerebrovascular lesions, brain inflammation and hydrocephalus. Half life is only 1.7 hours, check quickly and safely.
2.3 Renal scan and renal function assessment
In DTPA is excreted through glomerular filtration and belongs to rapid renal imaging agents. It can be used to evaluate renal function, detect renal artery stenosis and urinary tract obstruction, and provide important information for the diagnosis of urinary system diseases.
2.4 Placental scan and cardiac blood pool imaging
After intravenous injection of radioactive indium chloride (¹¹³ ᵐ InCl3) injection, due to the abundant blood in the placenta, the radioactivity in the placenta is significantly higher than in other parts of the uterus.
The position information of the placenta can be obtained from the surface using a scintillation probe, which is widely used for obstetric placental localization diagnosis. At the same time, it can also be used for cardiac pool scanning and cardiac function testing, with a half-life of 1.7 hours, and can be completed by intravenous injection of 2-4mCi/time.
2.5 Bone scan
Indium-113m labeled indium phosphate colloid can be used for bone scanning to diagnose bone metastases, osteomyelitis and other bone diseases. Intravenous injection of 5-8mCi/time, with a maximum injection volume not exceeding 10mL.

And can be used as efficient catalysts for CO ₂ reduction to methanol, with a Faraday efficiency of over 90%, providing a new path for achieving carbon neutrality goals.
3.3 Flexible electronics and self-healing materials
The stretchable circuit made of indium gallium alloy is applied in smart watches, electronic skins, and stretchable nerve repair devices, representing the development direction of the next generation of flexible electronic technology.
4. Aerospace and Defense
4.1 Rocket nozzle coating
Indium based alloys can withstand temperatures up to 1800 ℃ and are used for coating rocket engine nozzles to protect engine components from working properly under extreme high temperatures.
4.2 Control rods for nuclear reactors
Indium chloride has excellent neutron absorption ability and is used as a control rod material for nuclear fuel rods. It can accurately adjust the chain reaction rate and is an important guarantee for nuclear safety.
At present, the methods for preparing anhydrous InCl3 abroad mainly include direct chlorination of metal indium, decomposition chlorination of oxide and heating dehydration of hydrate. These preparation methods require high purity of raw materials and reagents, strict temperature control, complex equipment, low yield, difficult post-treatment and serious environmental pollution.
It has been reported that organic solvents such as amine, formamide and kerosene are used to remove crystal water from crystal chlorides to prepare anhydrous chlorides. Dehydration of MgCl2 · 2H2O with n-butanol to prepare anhydrous MgCl2 was also reported. This product is usually synthesized by direct reaction of indium and dry chlorine at 150 ~ 300 ° C. Or with indium trioxide and thionyl chloride. The pure product was purified by sublimation (300.degree. C.).
Indium dichloride synthesis method I:
Place indium trichloride and stoichiometric metal indium in a evacuated glass container. If they are completely melted, indium dichloride will be generated. The product can be refined by vacuum distillation.
While introducing hydrogen mixed with 15% hydrogen chloride, indium trichloride is heated to more than 600 ℃, and pure indium dichloride can be prepared by this reaction. At this time, it is heated with a weak red flame to make it react. It is not necessary to completely remove moisture and oxygen.
The product was heated at a temperature slightly higher than the melting point for 15 min. Meanwhile, in order to remove hydrogen chloride, nitrogen can be slowly introduced. If the light yellow melt is cooled down, it solidifies into a glassy solid.
Indium trichloride is synthesized by direct reaction of indium metal and dry chlorine at 150 ~ 300 ℃. Or by reacting indium trioxide and thionyl chloride. The pure product was purified by sublimation (300 ℃).
Method 2 for the synthesis of indium dichloride:
The direct chlorination method of indium metal is a method for preparing metal chlorides, which generates corresponding chlorides by directly reacting the metal with chlorine gas.
Step 1: Prepare the required raw materials
Indium metal:
With a purity of over 99.99%, usually provided in bulk or powder form.
Chlorine gas:
With a purity of over 99.99%, it undergoes dehydration treatment to remove moisture from it.
Reactor:
A reactor made of hard glass or quartz to ensure good chemical stability at high temperatures.
Auxiliary materials:
High-temperature furnace, thermocouple, inert gas (such as argon or nitrogen), etc.
Step 2: Experimental preparation
Clean the reactor thoroughly to ensure there are no residues.
Place the metal indium into the reactor and ensure that it is evenly distributed at the bottom of the reactor.
Seal the reactor and introduce inert gas to remove air.
Check if the thermocouple is correctly placed in the reactor and connected to the temperature controller.
Step 3: Heating reaction
Heat the reactor to the desired temperature (usually 500-600 ℃).
When the temperature reaches the set value, introduce chlorine gas into the reactor to ensure that the chlorine gas is evenly distributed on the surface of the metal indium.
Observe the reaction situation.
When the metal indium is completely converted to chloride (usually taking several hours), stop heating and let the reactor cool naturally.
During the cooling process, chlorine gas will gradually escape to obtain the required product.
The chemical equation is 3In+3Cl2 → InCl3
Step 4: Product Collection and Purification
After the reactor cools to room temperature, open the reactor and collect the generated product.
Preliminary purification of the collected product to remove impurities. Purification can be achieved through methods such as recrystallization and chromatographic separation.
Dry the purified indium chloride to remove any moisture.
Store the dried product in a dry and dark place to avoid moisture absorption and deterioration.
