Calcium cyanamide Granule

Product introduction 

Calcium cyanamide granular, with the chemical name of cyanamide calcium, have the molecular formula of CaCN₂ and the number of 156-62-7. It is a white or gray granular solid, and the industrial product is a grayish-black powder with the smell of carbide or ammonia. The apparent density is 0.9-1.1, sublimation at 1000℃, and the melting point is 100℃. It is insoluble in alcohol and slightly soluble in water, with hygroscopicity. When it meets water, it decomposes into ammonia gas is toxic to human body.

The uses of calcium cyanamide particles are extensive, mainly including: Agricultural use: Calcium cyanamide particles are anine nitrogen fertilizer, which can provide nitrogen to promote plant growth. In addition, it also has the effect of killing insects, sterilizing and weeding, and is often used control soil pests and diseases. Calcium cyanamide reacts with water in the soil to generate Calcium hydroxide and cyanamide, and cyanamide hydrolyzes to urea, and finally decomposes into ammonia, which is absorbed by plants. At the same time, calcium cyanamide can prevent and control a variety of vegetable pests diseases, eliminate soil acidification, reduce certain heavy metal pollution in the soil, improve the soil, and alleviate soil salinity obstacles.

Industrial use: Calcium cyanide particles are cyanamide chemical raw materials, which are used in the production of cyanamide, dicyanamide and other chemical products, and can also be used raw materials for the synthesis of thiourea, guanidine salt, etc. Personnel should wear protective equipment when using calcium cyanamide particles to avoid contact with the skin and inhaling dust.
