No qualitative white powder. Relative density 4.50. Melting point 1580 ℃. 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.


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.



"YLFT" precipitated barium sulfate 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 a white filler, can also be used as a filler for rubber and paper, can increase its weight and smoothness. Used as filler, brightening agent and weighting agent in rubber, plastics, paper making, paint, ink, coating and other industries. Used as a fining agent in glass products, can play the role of 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.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
