CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Barium sulfate appears as white or yellowish odorless powder or small crystals. Mp: 1580 °C (with decomposition). Density: 4.25 -4.5 g cm-3. Insoluble in water, dilute acids, alcohol. Soluble in hot concentrated sulfuric acid. Used as a weighting mud in oil-drilling, in paints, paper coatings, linoleum, textiles, rubber. Administered internally ("barium cocktail") as a radio-opaque diagnostic aid. |
