calcium cyanamide fertilizer

Calcium cyanamide is an important nitrogen fertilizer. The nitrogen cannot be absorbed by plants directly, but can only be absorbed by plants through the conversion of water and carbon dioxide. It is used as a base fertilizer and suitable for acid soil. Reacting with water to produce ammonia and calcium carbonate is a method of producing synthetic ammonia. It can also be used as a defoliant or herbicide. In the chemical industry, it is the raw material of cyanamide, dicyandiamide, melamine, which can be further processed into thiourea and guanidine. In the iron and steel industry, it is used as nitriding agent and cast iron desulfurizer for carbon steel and low alloy. In waste treatments, it can be used to remove formaldehyde in wastewater. The other important use is for the manufacture of pesticide.

Calcium cyanamide, also known as Lime nitrogen, is a kind of dark gray or black-gray powder or granules. The molecular formula is CaCN₂, molecular weight is 80.11. Relative density is 2.29, melting point is 1300℃, and it is begin to sublimation began at temperature more than 1150℃. Pure products are colorful crystals. Calcium cyanamide is light in texture, slightly soluble in water, insoluble in alcohol, easy to absorb water.

As a slow-release nitrogen fertilizer, Granular Calcium Cyanamide / Lime Nitrogen can increase crop yield and effectively kill harmful bacteria and insects, optimize soil structure, eliminate soil hardening, alleviate soil acidification, and supplement soil with calcium and nitrogen.
