Characteristic
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water.
Chemical formula：BaSO4
Molar mass：233.38 g/mol
Appearance：white crystalline
Odor：odorless
Density：4.49 g/cm3
Melting point：1,580 °C (2,880 °F; 1,850 K)
Boiling point：1,600 °C (2,910 °F; 1,870 K) (decomposes)
Solubility in water：0.0002448 g/100 mL (20 °C)
0.000285 g/100 mL (30 °C)
Solubility product (Ksp)：1.0842 × 10−10 (25 °C)
Solubility：insoluble in alcohol, soluble in concentrated, hot sulfuric acid
Magnetic susceptibility (χ)：-71.3·10−6 cm3/mol
Refractive index (nD)：1.636 (alpha)
Crystal structure：orthorhombic
Application
It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.
