In the field of materials science, barium sulfate is highly valued for its radiopacity, which means it is virtually impenetrable to X-rays and other forms of radiation. This property makes it an ideal component in the manufacturing of certain types of glass, ceramics, and radiopaque plastics. These materials are for applications requiring transparency to visible light while blocking radiation, such as in radiation shielding windows and protective glasses used in X-ray rooms and nuclear facilities. Barium sulfate is also extensively used as a pigment in paints, coatings, and plastics due to its excellent light reflectance, chemical inertness, and ability to improve the material′s surface properties. In paints and coatings, it contributes to color stability, brightness, and resistance to weathering and UV light. In plastics, it enhances the physical properties of the final product, such as hardness and dimensional stability, while maintaining the material′s color and brightness.
