|
| Formula: | BaH2 |
| Molecular Weight: | 139.38 |
| Synonyms: | Bariumdihydride; Barium hydride |
| Density: | g/cm3 |
| Melting Point: | 675°C (dec.) |
| Boiling Point: | °Cat760mmHg |
| Flash Point: | °C |
| Solubility: | decomposes in water to Ba(OH)2+H2; decomposes in acids [CRC10] |
| Risk Codes: | 15 |
| Safety: | A poison. Rapidly decomposed by water and acids. In powder form, it ignites spontaneously in air and reacts vigorously with water. Coarser material ignites when heated in oxygen. Moisture-sensitive, reacts with H2O with formation of Ba(OH)2 and H2. Decomp on heating with evolution of H2 gas and formation of Sr. It is incompatible with water; acids; and metal halogenates. A dangerous fire hazard because moisture may cause it to ignite. To fight fire, use dry chemical, graphite, CO2. See also BARIUM COMPOUNDS (soluble) and HYDRIDES. |
