Calcium Formate Uses




Calcium formate is a calcium salt commonly obtained by reacting calcium oxide or calcium hydroxide with formic acid. It appears as a white, crystalline powder that is highly soluble in water. This compound has a variety of uses in construction, industrial and agricultural applications.
This compound is valued for its unique properties, such as compatibility, solubility, and heat resistance. The most common uses of calcium formate include the following:
Calcium Formate in Concrete
Calcium formate has many uses in the construction industry. It is primarily used as an additive in grout and cement to accelerate the curing process and improve the strength of the final product.
When added to concrete formulations, calcium formate can enhance the early strength development of the material. This is beneficial in applications where rapid strength gain is needed, such as rapid-setting repairs and precast concrete products.
Adding calcium formate to concrete mixtures can also help decrease water demand, allowing for a lower water-to-cement ratio. This leads to improved workability and a more durable final product. Additionally, calcium formate can contribute to the overall durability of concrete by minimizing the permeability of the concrete formulations.
Agriculture
In agriculture, calcium formate is typically used as an animal feed additive. It is added to livestock feed to provide a supplemental source of calcium, which is vital for skeletal growth and muscle contractions. When added to animal feed, calcium formate ensures sufficient calcium absorption for livestock, especially during periods of high calcium demand like lactation and pregnancy.
This compound can also help prevent and treat calcium deficiency-related issues in livestock, which can cause muscle weakness and other health issues. Calcium formate can help stimulate the growth and overall health of livestock by promoting optimal skeletal development, muscle function, and nutrient absorption.
Leather Industry
In the leather industry, calcium formate is primarily used as a bating agent in the leather tanning process. Bating is the treatment of hides with enzymes to remove unwanted protein materials such as leftover flesh and hair roots. This leads to a cleaner and more uniform leather.
Calcium formate is used as a PH regulator and buffering agent to adjust and stabilize the pH of the leather during different stages of the tanning process. This helps maintain the desired pH range, which is essential for optimal protein structure and the efficiency of subsequent tanning operations.
Gypsum-Based Materials
Calcium formate serves as a fire-retardant additive in gypsum-based materials like drywall and gypsum boards. When included in these materials, calcium formate helps improve the flame-retardant and fire-resistance properties of the final product.
This compound also has a high heat absorption ability. It can take up heat from the fire, preventing it from spreading to other parts of the gypsum material or the surrounding environment.
Benefits of Calcium Formate as an Animal Feed Additive
Calcium Formate is known to improve the digestive health of animals. It acts as an acidifier, reducing the pH of the animal’s stomach, which aids in the digestion of feed. This can result in better nutrient absorption and overall health.
Calcium Formate has antimicrobial properties that can help to ward off the growth of harmful bacteria in the animal’s digestive system. This can reduce the risk of infection and illness in animals.
Calcium Formate can increase feed conversion efficiency, which means that animals can produce more meat or milk from the same amount of feed. This could lead to increased productivity and profitability for farmers.
Calcium Formate is a biodegradable and environmentally friendly compound. Its use can help to reduce the environmental impact of animal farming.
Calcium Formate can improve the growth rate of animals, resulting in larger and healthier livestock.

Calcium Formate Production Process
Reaction Principle
As formic acid is stronger than carbonic acid, formic acid reacts directly with calcium carbonate to produce calcium formate, Its reaction formula is: CaCO3+2HCOOH = Ca(HCOO)2 +CO2↑+H2O
The Main Raw Materials and Specifications
1)Formic acid: Formic acid content ≥ 85.0%, Heavy metal (Pb) ≤ 0.001%.
2) Heavy calcium carbonate: Calcium carbonate content ≥ 95%, fineness 200 mesh, heavy metal (calculated as Pb) ≤ 0.002%, magnesium content ≤ 2%, hydrochloric acid insoluble matter ≤ 0.5%, arsenic (AS) ≤ 0.002%.
Production Process
First, Add the raw heavy calcium carbonate powder to the reaction tank, and add an appropriate amount of mother liquor, then start stirring. Added dropwise concentrated formic acid to the reaction tank to a pH of 4 to 4.5 at room temperature, and the reaction is further continued for 15 minutes. Sand products of calcium formate are produced after centrifugation, air-flow dried and packaged, while mother liquor is recycled.
Production Process Conditions
1)In theory, the molar ratio of heavy calcium carbonate to formic acid is 1:2. In the course of the reaction, a large amount of CO2 will take away a small amount of formic acid, resulting in loss of formic acid. In addition, in order to ensure that the water-insoluble substances in the product are qualified, an excess of formic acid is required. Through the exploration of production, it is determined that the suitable material ratio of heavy calcium carbonate to formic acid is heavy calcium carbonate (95%): formic acid (85%)=1:0.83 weight ratio. The reaction was carried out at room temperature, stirring speed 60 r/min, reaction time 60 min.
2)Centrifugation: The calcium formate formed by the reaction is a uniform crystalline granule, which is particularly prone to dehydration. A three-legged centrifuge is used for dehydration in the production. The type of filter fabric used is polyester plain 260. Centrifugal dehydration time is 15min, wet material moisture content is ≤ 5%.
3)Dry packaging: Wet material crystallizes well, the water content is low. Tubular air dryer is selected and used in the production, with diameter φ300mm, length 20m, air volume 3 000m3 / h, drying temperature 150 ~ 180 °C. The packaging is 25kg woven bag lined with plastic bags.
Calcium Formate Formula: How Much to Use?
For Cement
The optimal dosage of calcium formate depends on several factors, including the type of cement used, the ambient temperature, and the desired setting time. However, as a general rule, a dosage of 0.5% to 1% by weight of cement is recommended.

For Animal Feed Usage
Recommendations: Following the recommended dosage and usage instructions is essential when using Calcium Formate as an animal feed additive. The EU recommended dosage of 15 grams of CF per kg of feed can significantly reduce PH. And it is safe for most animals to add to their feed. The amount of Calcium Formate added to animal feed can vary depending on the species and the desired outcome.
Generally, it is recommended to add between 0.5% to 1.5% Calcium Formate to the animal’s feed. However, consulting with a veterinarian or animal nutritionist is essential to determine the appropriate dosage for specific animals.
This is a general guideline, and it is always recommended to consult a professional and perform testing to determine the optimal amount for your specific application. Following the manufacturer’s instructions when using calcium formate is critical, and testing its effectiveness in small batches before scaling up production is critical.
Handling and Storage of Calcium Formate Power
1)Avoid dust formation.
2)Measures to prevent fire as well as aerosol and dust generation
3)Removal of dust deposits.
4)Advice on general occupational hygiene: Wash hands before breaks and after work.
5)Keep away from food, drink, and animal feedingstuffs.


1)Store in a dry place.
2)Incompatible substances or mixtures
3)Observe hints for combined storage.
