1, White to light yellowish white powder or lump. Strongly alkaline. Exposed to the air to absorb water and carbon dioxide. Contact with moisture to form barium hydroxide and release heat. At 450 ° C, it combines with oxidation to form ruthenium peroxide, and at 600 ° C, it is reduced to ruthenium oxide. It is soluble in water and dilute acid, but it is soluble in methanol or ethanol to form hydrazine alkoxide. The relative density is 5.72. The temperature of 1923 ° C. The boiling point is about 2000 ° C. The refractive index is 1.98. Toxic, half lethal dose (mouse, subcutaneous) 50mG/kG.
2, Used for glass, ceramic industry, also used in sugar beet sugar refining. BeiYan barium and peroxide is manufacturing of raw material. Still can be higher and dehydrated agent desiccant, etc.
3, Dehydrating agent. A desiccant for gases and solvents. Preparation of cerium salts and cerium peroxide. Glass industry.
