Nature: colorless crystals or Orthorhombic Department of amorphous white powder. Relative density of 4.50 (15 ℃). Melting point 1580 ℃. Hardly soluble in water, ethanol and acid. Soluble in hot concentrated sulfuric acid, the dry caking easy. 600 ℃ when the carbon can be reduced to barium sulfide.

Uses: used for paint, printing ink, plastic, rubber and raw materials for batteries or filling machines, printed paper, like paper and copper surface coating agent, the textile industry used sizing agent. Clarifying agent for glass products, will be able to take anti-foaming and increase the role of gloss. Can be used as anti-radiation protective wall material used. Also used in ceramics, enamel, spices and pigments industries. Is also the manufacture of other barium salts of the raw materials.

Packaging and storage: use plastic bags lined with polyethylene bags latex or packaging, bag net weight 25kg. Stored in the coffers dry. As white pigment, the non-ferrous items can not be shipped a total mixed storage to prevent contamination colors, loading and unloading to take light caving light, to prevent damaged packaging.
