CaCN2 molecular 80.10
colorless hexagonal crystals Department. Because of industrial products containing impurities such as carbon dark powder or granules. A carbide or ammonia odor. Apparent density 0.9-1.1g/cm3. Sublimation 1090 ° C 1300 ° C melting point. With water decomposition of ammonia, the volume, easily trigger an explosion. Toxic! People easily lead after inhaling respiratory disorders spasm. Contain impurities such as calcium carbide, or when a small amount of calcium phosphate, water vulnerable to burning.
agriculture is the application - basic types of fertilizer. For acidic soil, which can and soil acidity, soil acidity could be utilized to eliminate toxicity, in urea into the process, the intermediate product is toxic to crops, in general only as a basic, not directly for top dressing fertilizer and species; As for alkaline soil, due to slow decomposition, it is easy to create double cyanamide, it is not appropriate application. Efficient production is a low toxicity pesticides carbendazim, herbicides, fungicides, insecticides of the main raw material. In addition, organic or plastic industries and the basic industrial raw materials for the production of dicyandiamide, melamine, cyanide melt, thiourea, such as plexiglass.
