The production method, barium carbonate Shanghai xin chemical industry

barium carbonate is the barium salt, toxicity, and to store in a cool, ventilated warehouse, not to be confused with other items. Barium carbonate with light and heavy, in glass, electronics, ceramic glaze, etc all have applications, so how barium carbonate preparation of success?

today, there are three ways to preparing barium carbonate: carbonization method and double decomposition method and toxic heavy petrochemical method.

a carbonization method

carbonization method is the so-called barium sulphide solution into carbon dioxide for carbonation, produce barium carbonate slurry, the filtering and drying process can get barium carbonate products.

BaS+CO2+H2O=BaCO3↓ + H2S

double decomposition method double decomposition reaction is performed with barium sulphide and ammonium carbonate, filtered, dry can.

BaS+( NH4) 2CO3=BaCO3↓ + ( NH4) 2 s

three poisonous heavy petrochemical method

toxic petrochemical method is to response generated witherite mineral powder and ammonium salt soluble barium salt, ammonium carbonate and recycle, barium carbonate slurry in soluble barium salt with ammonium carbonate, filtered, dry can get.

in the industrial, carbonization process method and double decomposition method is simple, but need to pressure equipment, a long process, equipment, the high cost. So poisonous heavy petrochemical industrial general with the improved method, to make full use of resources, reduce the cost.
