Compound uses

Barium sulfate is used as a filler in plastics and as a component of oil well drilling fluid to increase the density.
It is used in brake linings, acoustic foams and powder coatings
Barium sulfate is also used during the procedure of the soil pH test. In this test it is used so that it precipitates out any particles (usually clay particles) which would otherwise 'cloud' solution preventing one from seeing the color of the pH indicator i.e. the result of the test.
It is used in root canal filling.
In colorimetry barium sulfate is used as a near-perfect diffuser when measuring light sources.
