PointsSubtype:BaSO4

 

PointsSub-quantity:233.39 (according to the 1979 International Atomic Scale)

 

C A S No.13462-86-7       

 

EINECS号236-664-5     

 

H.S. Encoding:2833270000

 

Performance:No qualitative white powder. relative density4.50. Melting Point1580C. Insoluble in water, ethanol and acid. Soluble in concentrated sulfuric acid, easy to agglomerate when dry. It is cothermally reduced with carbon to barium sulfide. In the air in the case of hydrogen sulfide and toxic gases do not change color.

 

Use:Widely used in various coatings, plastics, rubber, paint, ink, insulating tape, ceramics, batteries, enamel and other industries. Can be used for acid-resistant rubber products and general products. It can also be used as a surface coating agent, a sizing agent, a weighting agent, etc.

 

Advantages:“YLFT”precipitated barium sulfateIt has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high specific gravity and good whiteness.Can be used as whiteFillIt can also be used as a filler for rubber and paper making, which can increase its weight and smoothness. Used as filler, brightening agent and weighting agent in rubber, plastic, paper making, paint, ink, coating and other industries. InGlass products are used as a fining agent, which can defoaming and increase gloss. It can be used as a protective wall material for radiation protection. Also used in ceramics, enamel, spices and pigments and other industries. It is also a raw material for the manufacture of other barium salts.
