Calcium Formate Powder is an important inorganic chemical product with the molecular formula Ca (HCOO) ₂ and CAS number 544-17-2. It has the appearance of white crystalline powder, is easily soluble in water, has stable properties, and is widely used in various fields such as feed, construction, agriculture, leather, petroleum, food, etc. The following are its main uses and applications in different industries:
Calcium formate is added to feed in a neutral form. After animals consume it, trace amounts of formic acid are released through biochemical reactions in the digestive tract, reducing the pH value of the gastrointestinal tract, promoting the growth of beneficial bacteria, inhibiting the proliferation of harmful bacteria, and improving intestinal health. For example, adding 1.0% to 1.5% calcium formate to piglet feed can significantly improve feed conversion rate, promote growth, and reduce diarrhea. The calcium element in calcium formate exists in organic form and is easily absorbed and utilized by animals. Research has shown that adding calcium formate can increase daily weight gain of piglets by 7% to 12%, feed conversion rate by 4% to 9%, and protein and energy utilization efficiency by more than 10%, respectively. The antibacterial effect of calcium formate can reduce intestinal infections in animals, lower disease incidence, and improve survival rate.
Building material additives
Calcium formate is widely used in the construction industry as a cement early strength agent, lubricant, and antifreeze, and is widely applied in industries such as dry mixed mortar, concrete, wear-resistant materials, flooring, etc. Calcium formate can promote the hydration reaction of tricalcium silicate (C3S) in cement, significantly improving early strength. For example, adding 0.3% to 0.5% calcium formate during winter construction can quickly solidify concrete at low temperatures, shorten the setting time, and avoid frost damage. Its lubricating effect can reduce the friction between concrete and molds, improve demolding efficiency, and make the concrete surface smooth and flat. Meanwhile, its anti freezing performance can prevent moisture from freezing at low temperatures, ensuring the normal development of concrete strength.
For example, dry mixed mortar: the addition amount is 0.5%~1.0% to improve the bonding strength and crack resistance of the mortar. Concrete: with an addition amount of 0.3% to 0.8%, suitable for road, bridge, tunnel and other engineering projects. Wear resistant materials: mixed with cement and aggregates to improve the wear resistance and compressive strength of the floor. At the same time, it should be noted that excessive addition may lead to a decrease in the later strength of concrete, and the dosage should be strictly controlled. The lower the temperature, the more significant the early strength effect of calcium formate, and the dosage can be appropriately reduced in summer.
Calcium formate is used as a calcium fertilizer and soil amendment in agriculture, with the functions of supplementing calcium, regulating soil acidity and alkalinity, and promoting crop growth. The calcium element in calcium formate is easily absorbed by plants and can effectively prevent physiological diseases caused by calcium deficiency in crops, such as tomato navel rot and apple bitter acne. The weak acidity of calcium formate can neutralize alkaline soil, improve soil structure, and enhance soil fertility. For example, foliar spraying: diluted and sprayed on crop leaves to quickly replenish calcium elements. Base fertilizer application: mixed with organic fertilizer and applied to the soil to improve the soil environment. When applied simultaneously, adjustments should be made according to soil type and crop requirements to avoid excessive soil acidification. The application effect is better during critical periods of crop growth, such as flowering and fruiting.
Leather industry
Calcium formate, as a tanning agent and neutralizer in leather manufacturing, can improve the softness, elasticity, and durability of leather. Calcium formate binds with collagen in leather to form a stable cross-linked structure, enhancing the physical properties of leather. Calcium formate can adjust the pH value during leather dyeing and finishing processes to ensure even adhesion of dyes and finishing agents. For example, high-end leather: used to make leather shoes, leather jackets, leather goods, etc., to improve product quality. Industrial leather: used for car seats, sofas, etc. to improve wear resistance and anti-aging performance. During the tanning process, it is necessary to strictly control the temperature, time, and pH value to avoid the leather becoming too hard or deformed. The use of calcium formate must comply with environmental standards and reduce wastewater discharge.
Calcium formate, as a drilling fluid additive in petroleum drilling, can improve the stability and lubricity of drilling fluids. Calcium formate can adjust the pH value of drilling fluid, prevent wellbore collapse, and ensure drilling safety. Reduce the friction between the drill bit and the rock, improve drilling efficiency, and extend the service life of the drill bit. For example, in deep well drilling, calcium formate can maintain the stability of drilling fluid performance in high temperature and high pressure environments. Shale gas development: prevent shale hydration and expansion, and avoid wellbore instability. At the same time, it should be used in conjunction with other drilling fluid additives to avoid sedimentation or stratification. After drilling is completed, the waste drilling fluid needs to be treated harmlessly.
food industry & Other applications
Calcium formate, as a preservative and acidity regulator in food, meets food safety standards. Calcium formate can inhibit the growth of mold and yeast, and extend the shelf life of food. It is used in jam, beverage and other foods to adjust pH value and improve taste. For example, baked goods: prevent bread and cake from getting moldy. Dairy products: Extend the shelf life of yogurt and cheese. At the same time, it is necessary to strictly follow national standards to avoid exceeding them. The use of calcium formate should be clearly labeled on food packaging.
Calcium formate can be used as a desulfurizer to remove sulfur dioxide from flue gas and reduce environmental pollution.

The discovery of Calcium Formate Powder is closely related to the development of chemical science. In the late 18th and early 19th centuries, chemists began to systematically study the properties and preparation methods of inorganic compounds. Formic acid (HCOOH), as the simplest carboxylic acid, was obtained by distilling ants as early as the 17th century and was named "formic acid" due to its early extraction from ants. The chemical properties of formic acid are gradually being revealed, but the systematic study of its salts lags behind the acid itself. In 1789, French chemist Antoine Laurent de Lavoisier first classified elements into gases, metals, non metals, and alkaline earth metals in his work, laying the foundation for subsequent research. However, at that time, the understanding of alkaline earth metals (such as calcium) was still limited to mineral forms (such as limestone), and systematic research on their elemental and compound forms had not yet been conducted.
At the beginning of the 19th century, British chemist Humphry Davy separated various alkali metals and alkaline earth metals through electrolysis, which promoted the key progress in the preparation of calcium formate. In 1808, David successfully produced calcium amalgam by electrolyzing a mixture of lime (CaO) and mercury oxide (HgO), and subsequently separated metallic calcium through distillation. This breakthrough achievement not only established the existence of calcium as an independent element, but also provided raw materials for the subsequent preparation of calcium salts. David's electrolysis method is based on the invention of the Voltaic Pile, which uses direct current to decompose compounds in molten or solution. Although the early experimental conditions were rudimentary (such as using platinum electrodes and inefficient power sources), David significantly improved the efficiency of metal precipitation by optimizing the electrolyte composition (such as adding mercury to form mercury amalgam). This technology was later widely applied in the industrial production of metals such as sodium, potassium, and magnesium. In the 20th century, the production technology of calcium formate underwent two major innovations:
- Optimization of Neutralization Method: In the early 20th century, chemists improved the purity of calcium formate (reaching over 98%) through continuous crystallization and recrystallization techniques, and developed reactors suitable for large-scale production.
- Industrialization of the double decomposition method: In the 1950s, with the development of ion exchange membrane technology, the yield of the double decomposition reaction was greatly improved and the production cost was reduced. Calcium formate began to be widely used as a building additive (such as cement early strength agent) and feed additive.
In the field of construction, calcium formate as an early strength agent can accelerate cement hydration reaction, improve early strength, and is particularly suitable for low-temperature construction. In the feed industry, calcium formate promotes beneficial bacterial growth and increases feed conversion rate by regulating the pH value of the animal gastrointestinal tract.
Calcium formate powder is a versatile and valuable compound with diverse applications across various industries. Its unique chemical properties, including solubility, stability, and reactivity, make it an essential additive in construction, agriculture, leather processing, and other sectors.
