barium sulfate grinding process
Barium sulfate - Wikipedia
Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. Barite is processed by thermo-chemical sulfate reduction (TSR), also known as carbothermal reduction (heating with coke) to give barium sulfide: BaSO4 + 4 C → BaS + 4 COIn contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxid

Barium sulfate is used to identify the teeth from the diagnostic wax-up in a 20% BaSO4 solution. If a soft tissue (flapless surgery) template is to be made, teeth are ideally identified with a 20% BaSO 4 solution, and the base (soft tissue) uses a 10% mix. This allows for differentiation of the teeth from the soft tissue.
