For industial usage, , it is used as a filler for white pigments, paper and rubber.
Applications
1. In the medical field, barium sulphate is used as a dual X-ray contrast agent.

It is commonly used for gastrointestinal imaging.
2. In paints application, barium sulfate is better than that of most other filling powders. It has the characteristics of low coagulation, low light dispersion and fine particles.
