This product is a kind of amorphous white powder with a proportion of: 4.43 and a melting point of 1740 „ƒ (90 atmospheric pressure). It will be decomposed in the temperature of 1450 „ƒ while losing the carbon dioxide. Barium carbonate doesn’t dissolve in water and alcohol, but dissolves in acid and ammonium chloride solution. It is toxic for taking. While entering into the stomach, it dissolves in acid and becoming soluble barium chloride, which can lead to poisoning. Therefore, it is a kind of poisons.Packing Specification¼š lined with plastic bags with plastic woven packaging outside.
