Weight: 233.40 (in 1979 the international atomic weight table) Characteristics: no qualitative white powder. Non-toxic, insoluble in water, dissolved in smoke sulfuric acid, hydrochloric acid-soluble in boiling. Chemical properties of stability, and a total reduction of carbon sulfide barium. In the case of hydrogen sulfide in the air or toxic gases do not change color.
Use: for coatings, paints, inks, rubber, plastics, insulation with the filler.
