Introduction
Amorphous precipitated barium sulfate is a white powder , slightly soluble in water , soluble in acid . 0.0024g/100g solubility in water . It can dissolved in hot concentrated sulfuric acid . Slightly soluble in water and insoluble in alcohol and acid . It has the character of chemically inert , good stability , acid , alkali , moderate hardness , high specific gravity , good whiteness . As a white filler , it can also as filler for rubber and paper , to increase the products weight and smoothness . In the rubber , plastics , paper , paint , ink and other industries , it can used as a filler , lightening agents , weighting agents . Used as a clarifying agent in glass , it can play the role of anti-foaming and increase the gloss . It also used as an anti-radiation protective wall material and in ceramics , enamel , spices , pigments and other industries .
