Application:

1.Barium carbonate can be used in the manufacture of electronic ceramics, PTC thermistors, capacitors and other electronic components.

2.Barium carbonate is mainly used in the manufacture of optical glass, picture tube glass, barium magnetic materials and capacitors, etc. It is also used in iron and steel carburizing and metal surface treatment. Is the manufacture of other barium salts and ceramics, enamel, paint, coatings, rubber, electrode raw materials.

3.Barium carbonate can also be used as water purifier, rodenticide and catalyst for oxidation reaction.

 

Production method of barium carbonate:

Carbonization method carbonized the barium sulfide solution (see barium sulfide preparation) through ^ CARBON dioxide gas, and obtained the barium carbonate slurry after desulfurization washing, vacuum filtration, drying and grinding at 300℃, to produce barium carbonate products. BaS+CO2+H2O→BaCO3↓+H2S↑ Double decomposition reaction between barium sulfide and ammonium carbonate, and then after washing, filtering, drying Chemicalbook, etc. to obtain bismuth carbonate products. BaS+(NH4)2CO3→BaCO3↓+(NH4)2S toxin-sylvite conversion method reacts with ammonium salt to produce soluble barium salt, and at the same time, ammonium carbonate is recovered and used. Soluble barium salt is added to ammonium carbonate to precipitate out refined barium carbonate, which is filtered and dried to produce barium carbonate products. The mother liquor obtained shall be recycled and used.
