CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Barium peroxide appears as a grayish-white granular solid. Insoluble in water. Noncombustible, but accelerates the burning of combustible material. Mixture with finely divided combustible material may be explosive. Mixtures with combustible material may be ignited by friction or contact with moisture. |
|---|---|
| Color/Form | White or grayish-white, heavy powder |
| Odor | Odorless |
| Boiling Point | 800 °C (decomposes) |
| Melting Point | 842 °F (USCG, 1999) |
| Solubility | 0.091 g/100 g water at 20 °C |
| Density | 4.96 at 68 °F (USCG, 1999) - Denser than water; will sink |
| Stability/Shelf Life | Decomposes slowly in air. |
| Decomposition | The substance decomposes on heating and on contact with water or acids producing oxygen and hydrogen peroxide, which increases fire hazard. |
| Corrosivity | Corrodes metal slowly |
| Other Experimental Properties | Oxidizing material |
| Chemical Classes | Metals -> Peroxides, Metal |
