Audited Supplier | Industrial barium sulfate |
| Chemical formula: BaSO4 |
| Properties: white powder, non-toxic. Melting point is 1350°C, almost insoluble in water, ethanol and acid. It has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness (Mohs hardness 3~3.5), high gloss, high whiteness, and ability to absorb other harmful rays. |
| Application: Due to its excellent physical and chemical properties, barium sulfate has been widely used in powder coatings, engineering plastics, paints, inks, batteries, rubber, glass, cosmetics, friction materials and other fields. It is an ideal filling material. |
| Package: Net weight 25kg/bag |
