CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Calcium cyanamide, with more than 0.1% calcium carbide appears as a colorless to gray, odorless solid. May cause illness from ingestion. May irritate the skin. If exposed to water or high temperatures, calcium cyanamide may generate toxic and flammable fumes. Used to make pesticides and in fertilizers. |
|---|---|
| Color/Form | Pure calcium cyanamide occurs as glistening, hexagonal crystals belonging to the rhombohedral system |
| Boiling Point | Sublimes >2102 °F (NTP, 1992) |
| Melting Point | 2372 °F (NTP, 1992) |
| Solubility | Decomposes (NTP, 1992) |
| Density | 2.29 at 68 °F (NTP, 1992) - Denser than water; will sink |
| Vapor Pressure | 0 mmHg (approx) (NIOSH, 2023) |
| Other Experimental Properties | Sublimes at 1150-1200 °C; heat of formation from CaC2 + N2: -69.0 kcal/mole (25 °C); heat of fusion 1.29 cal/g; no known solvent will bring about soln without decomp; undergoes partial hydrolysis to the soluble calcium hydrogen cyanamide, a source of cyanamide ions; nonvolatile and noncombustible |
| Chemical Classes | Nitrogen Compounds -> Cyanamides |
