Barium carbonate

Our Barium carbonate is of 99.5%, it is amorphous white powder, toxic, the proportion is 4.43. It is almost insoluble in water (solubility in the water is 1.72 mg / 100 ml Water).But it can be dissolved in hydrochloric acid, nitric acid and acetic acid. about 1300 centigrade. It begins to decompose into barium oxide and carbon dioxide, its melting point is at 1740 centigrade (under 90 atmosphere Pressure).
Barium carbonate is an important mineral product, which can be used for color television picture tubes, magnetic materials, optical glass, ceramics, oil paint, carburizing steel, welding, paint of ceramics, rubber, paint, fireworks and other barium salt manufacturing and other industries.
