Molecular formula: BaSO4
CAS No.: 7727-43-7
H. S. Code: 2833270000
Product Description:
Precipitated barium sulfate is produced in advanced chemical precipitation method, good physical properties, low mechanical impurity, even fineness; White powder or paste, non-toxic, insoluble in water, soluble in fuming sulphuric acid, stable chemical property; Can absorb X-ray, and endow the materials with high density and surface finish, therefore widely used in paints, printing ink, coatings, plastics, rubber, chips, friction plate, ceramics, glass, electronics, cosmetics, pharmacy and food etc.
Appearance:
White oblique side crystallization or white amorphous powder.
Application:
Storage Battery:After modification, the product has ultra-fineparticle size and even distribution. In addition, it has good dispersion, noiron and is almost no discharge. It is an indispensable part of all kinds ofnegative active substances in lead-acid batteries. It is the most commonly usedinorganic expander in battery manufacturing. Due to the lattice parametersimilar to that of Lead(II) sulfate, itcan be highly dispersed in the negative active material, and has more crystalcenters during the discharge, which can better prevent the specific surfacearea of lead from shrinking, effectively delay the passivation of the plate,and make the battery start quickly and have a long life in use.
