| Chemical name | Calcium cyanamide | ||
| Molecular formula | CaCN2 | ||
| Molecular weight | 80.10 | ||
| Structural formula | Ca=N-C=N | ||
| Character | Industrial products are gray black powder with the smell of calcium carbide or ammonia. The pseudo specific gravity is 0.9-1.11000 ° C, sublimation, melting point 1300 ° C, insoluble in alcohol, but slightly soluble in water. It is hygroscopic and decomposes into ammonia in case of water, which is toxic to human body. | ||
