- Barium Sulphate is used as a high temperature oxidizer in certain pyrotechnic formulas, as barium compounds emit green light when burned.
- Barium Sulphate is frequently used clinically as a radio contrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as ‘barium meal’.
- Barium Sulphate mixtures are used as white pigment for paints. In oil paint, Barium Sulphate is almost transparent and is used as filler or to modify consistency.
- In photography it is used as a coating for certain photographic papers
- Battery manufacturing
- Barium Sulphate is used as filler in plastics and as a component of oil well drilling fluid to increase the density. It is also used in Episal Salt, brake lining, anacoustic foams, powder coatings and root canal filling.
- In colorimetry Barium Sulphate is used as a near-perfect diffuser when measuring light sources.
- In photography it is used as a coating for certain photographic papers.
- In metal casting, the moulds used are often coated with barium sulphate in order to prevent the molten metal from bonding with the mould.
