Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral "barite" can vary between red, yellow, gray or green, depending on impurities. Its density is 4.50 g/cm 3 and its refractive index is 1.64. It melts around 1580 °C but decomposes above 1600 °C.

To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts: BaS + H 2 SO 4 → BaSO 4 + H 2 S. Barium sulfate produced in this way is often called blanc fixe, which is French for "permanent white." Blanc fixe is the form of barium encountered in consumer products, such as paints.
