What are the main uses of OEM Calcium Cyanamide?
Aug 20, 2025| Calcium cyanamide, a chemical compound with the formula CaCN₂, has been a significant industrial chemical for over a century. As an OEM Calcium Cyanamide supplier, I've witnessed firsthand the diverse applications of this compound across various industries. In this blog, I'll delve into the main uses of OEM Calcium Cyanamide and explore how it contributes to different sectors.


Agriculture: A Fertilizer and Soil Amendment
One of the primary uses of OEM Calcium Cyanamide is in agriculture. It serves as a slow - release nitrogen fertilizer, providing a steady supply of nitrogen to plants over an extended period. Unlike some traditional nitrogen fertilizers, calcium cyanamide releases nitrogen gradually, reducing the risk of nitrogen leaching into the environment. This makes it an environmentally friendly option for farmers.
When calcium cyanamide is applied to the soil, it undergoes a series of chemical reactions. First, it reacts with water to form calcium carbonate and cyanamide (H₂NCN). Cyanamide then hydrolyzes to form urea, which is further broken down into ammonia and carbon dioxide by soil microorganisms. The ammonia is then available for plant uptake.
In addition to being a nitrogen source, calcium cyanamide also has other benefits for the soil. It can increase soil pH, making it suitable for acidic soils. The calcium in the compound helps to improve soil structure, enhancing water infiltration and root penetration. Moreover, it has some pesticidal properties. It can suppress the growth of certain soil - borne pathogens, nematodes, and weeds, reducing the need for additional chemical pesticides.
Industrial Applications
Steel Industry
In the steel industry, OEM Calcium Cyanamide plays a crucial role in the desulfurization process. Sulfur is a common impurity in steel, which can reduce the mechanical properties of the steel, such as ductility and toughness. Calcium cyanamide can react with sulfur in the molten steel to form calcium sulfide (CaS), which can be easily removed from the steel. This helps to improve the quality of the steel and makes it more suitable for high - performance applications.
The reaction mechanism involves the decomposition of calcium cyanamide at high temperatures in the molten steel. The released nitrogen can also have a beneficial effect on the steel's properties, such as increasing its strength and hardness.
Production of Chemicals
Calcium cyanamide is an important raw material for the production of various chemicals. It is used in the synthesis of melamine, a versatile organic compound used in the manufacture of plastics, adhesives, and flame - retardant materials. The process involves the reaction of calcium cyanamide with carbon dioxide and water under specific conditions to produce melamine.
Another chemical that can be derived from calcium cyanamide is dicyandiamide. Dicyandiamide is used in the production of pharmaceuticals, dyes, and explosives. The reaction of calcium cyanamide with water and an acid catalyst can yield dicyandiamide.
Environmental Applications
Wastewater Treatment
OEM Calcium Cyanamide can be used in wastewater treatment processes. It can react with heavy metal ions in the wastewater, such as lead, cadmium, and copper, to form insoluble metal cyanamides or metal hydroxides. These precipitates can then be easily removed from the water, reducing the concentration of heavy metals in the wastewater.
In addition, calcium cyanamide can also be used to treat wastewater containing organic pollutants. It can oxidize some organic compounds, breaking them down into simpler and less harmful substances. This helps to improve the quality of the wastewater before it is discharged into the environment.
Carbon Sequestration
Calcium cyanamide can also be involved in carbon sequestration efforts. When it reacts with carbon dioxide, it forms calcium carbonate and nitrogen. This reaction can be used to capture carbon dioxide from industrial emissions, reducing the amount of greenhouse gases released into the atmosphere. The calcium carbonate formed can be stored or used in other industrial processes, such as in the production of cement.
Comparison with Related Products
When comparing OEM Calcium Cyanamide with other related products, it has its unique advantages. For example, compared to Carborundum Diameter 60 Microns, which is mainly used in abrasives and refractory materials, calcium cyanamide has a broader range of applications in agriculture, steelmaking, and chemical synthesis.
Activated Carbon Pellets are commonly used for adsorption in environmental applications. While they are effective in removing certain organic and inorganic pollutants from air and water, calcium cyanamide has the added benefit of chemical reactivity. It can not only adsorb but also react with pollutants, providing a more comprehensive solution for environmental problems.
Conclusion
In conclusion, OEM Calcium Cyanamide is a highly versatile compound with a wide range of applications in agriculture, industry, and environmental protection. Its unique chemical properties make it an indispensable material in many processes. Whether it's improving soil fertility, enhancing the quality of steel, or treating wastewater, calcium cyanamide has proven its value time and time again.
