synthetic method
Carbon thermal reduction method:
Reduce TiO2 with carbon black, reaction temperature range is 1700-2100 ℃, chemical reaction equation is: TiO2(s)+3C(s)=TiC(S)+2CO(g).
Direct carbonization method:
Generate TiC by reacting Ti powder and carbon powder. The chemical reaction equation is: Ti(s)+C(s)=TiC. Due to the difficulty in preparing submicron sized metal Ti powder, the application of this method is limited. The above reaction takes 5-20 hours to complete, and the reaction process is difficult to control. The reactants agglomerate severely, requiring further grinding processing to prepare fine TiC powder particles. To obtain a purer product, it is necessary to purify the fine powder after ball milling using chemical methods.
Chemical vapor deposition:
This synthesis method utilizes the reaction between TiCl4, H2, and C. The reactants react with hot tungsten or carbon filaments, and TiC crystals grow directly on the filaments. The yield and sometimes even quality of TiC powder synthesized by this method are strictly limited. In addition, due to the strong corrosiveness of TiCl4 and HCl in the product, special caution should be taken during synthesis.
Sol-gel method:
A method of preparing small particle size products by thoroughly mixing and dispersing materials with a solution. It has the advantages of good chemical uniformity, small and narrow powder particle size distribution, and low heat treatment temperature, but the synthesis process is complex and the drying shrinkage is large.
Microwave:
Using nano TiO2 and carbon black as raw materials, utilizing the principle of carbon thermal reduction reaction, and utilizing microwave energy to heat the materials. In fact, it utilizes the dielectric loss of materials in high-frequency electric fields to convert microwave energy into thermal energy, enabling the synthesis of TiC from nano TiO2 and carbon.
Explosion impact method:
Mix titanium dioxide powder with carbon powder in a certain proportion, press it into a cylindrical shape with a diameter of 10mm × 5mm to prepare the precursor, with a density of 1.5g/cm3, and place it in a metal constrained outer cylinder in the laboratory. Put it into a self-made sealed explosion container for experimentation, and collect the detonation ash after the explosion shock wave is applied. After preliminary screening, large impurities such as iron filings are removed to obtain black powder. After soaking the black powder in aqua regia for 24 hours, it turned brown. Finally, it was placed in a muffle furnace and calcined at 400 ℃ for 400 minutes to obtain a silver gray powder.
High frequency induction carbon thermal reduction method:
Weigh and mix pigment grade titanium dioxide powder and charcoal powder in a molar ratio of 1:3 and 1:4, add them to a ball milling jar, and ball mill them on a planetary ball mill for 6-10 hours at a speed of 300-400 r/min. Then press the ball milled material into 2cm × 2cm ～ 2cm × 4cm blocks on a tablet press. Finally, load the material into a graphite crucible and place it in a high-frequency induction heating device. Use argon gas as a protective atmosphere, gradually adjust the current of the high-frequency induction device to 500A to cause carbon thermal reduction reaction of the material, and keep it warm for 20 minutes. After the insulation is completed, the reduced product is naturally cooled to room temperature in an argon atmosphere. The reduced product is taken out, ground and crushed to obtain ultrafine titanium carbide powder.
Metal thermal reduction method:
A solid-liquid reaction method, which is an exothermic reaction, has a low reaction temperature and low energy consumption. However, the raw materials are relatively expensive, and CaO and MgO in the products are pickled and cannot be recycled.
High temperature self propagating synthesis method:
The SHS method originates from exothermic reactions. When heated to an appropriate temperature, fine Ti powder has high reactivity. Therefore, once the combustion wave generated after ignition passes through the reactants Ti and C, Ti and C will have enough reaction heat to generate TiC. The SHS method reacts extremely quickly, usually in less than one second. This synthesis method requires high-purity and fine Ti powder as raw material, and the yield is limited.
Reaction ball milling technology method:
Reactive ball milling technology is a technique that utilizes chemical reactions between metal or alloy powders and other elements or compounds during the ball milling process to prepare the required materials. The main equipment for preparing nanomaterials using reactive ball milling technology is the high-energy ball mill, which is mainly used to produce nanocrystalline materials. The mechanism of reactive ball milling can be divided into two categories: one is mechanically induced self propagating high-temperature synthesis (SHS) reaction, and the other is reactive ball milling without significant heat release, which has a slow reaction process.
