CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Barium nitrate appears as a white crystalline solid. Noncombustible, but accelerates burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided, an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen produced in fires. |
