Other Names: Barite
Formula: BaSO4
Sp. Gr.: 4.4 (Powder)
Viscosity: Varies with concentration and liquid used to make slurry

Remarks: A fine, white, odorless powder. Practically insoluble in water and solvents; soluble in concentrated sulfuric acid. It is used as a pigment for paints, filler for plastics and inks and in the medical industry. Barium sulfate is abrasive.

Pump Notes: Cast iron construction is satisfactory. An abrasion resistant mechanical seal should be used for shaft sealing. Due to the abrasive characteristics of the liquid, design features to combat abrasion must be used.
