industrial grade barium nitrate Nature: Achromatous or white cubic crystals or powder. Its specific gravity is 3.24 (23°C) and melting point is 592°C. It is decomposed into oxides in combustion and gives out green flares. It is noxiousl. Applications: Used to manufacture barium oxide and barium peroxide, optical glass, pottery glazes, and used as explosives, additives for combustion, green-color fireworks, signal flares and flame tracers, also used in antisepsis, chemical agents and medication. And sometimes it is also used in low-temperature salt bath for metal heat treatment.
