Barium Sulfate is used as a pigment extender for coatings, plastics, rubber and chalks. Special grades are approved for pharmaceutical applications where the material is used in medical x-ray exams (it is an insoluble, inert, non-radioactive substance). The barium sulfate is more dense than the other tissues in the body making it possible to see organs and structures that cannot be seen otherwise.
