Barium sulfide is white or offwhite crystal powder, however industrial one is light brown or black powder or lump. It tend to absorb moisture and hydrolysis. In dry air, BaS oxidize to yellow or orange color. But in moisture air, it decompose to H2S, which is faster in acids. BaS is soluble in water. Its production method is same as calcium sulfide and strontium sulfide. Barium carbonate is the raw material.
