Product introductionAmorphous white powder. Relative density 4.50. Melting point 1580℃. Insoluble in water, ethanol and acids.Soluble in concentrated sulfuric acid.  It tends to agglomerate when dry.  Cothermal reduction with carbon to barium sulfide.  Hydrogen sulfide and toxic gases do not discolor in the air.

Introduction:“YLFT”Precipitation of barium sulfate Strong chemical inertness. good stability,Acid and alkali resistance,Moderate hardness,High specific gravity, whiteness and other advantages. Can be used as white filler. Can also be used as a filler for rubber and paper, Can increase its weight and smoothness. In rubber, plastic, paper, paint, ink, paint and other industries used as filler, lightening agent, weighting agent.  Used as a clarifier in glass products, Can play the role of defoaming and increasing luster. It can be used as protective wall material against radiation. Also used in ceramics, enamel, spices and pigments and other industries. It is also the raw material for making other barium salts.
