Why do we us barite/ baryte in lithopone paint?

Barium sulfide is an important chemical made from barite. When it is mixed with zinc sulfate, a chemical reaction ensues that results in an intimate mixture of barium sulfate and zinc sulfide called lithopone, which serves as a white pigment. Lithopone was used extensively to make white paint, but its importance for that purpose declined greatly after the introduction of titanium dioxide pigments. Lithopone has also been used in floor coverings and textiles. Barium sulfide and zinc sulfate have also been used to treat wooden artifacts to give them a marble-like finish.

Applications

Lithopone is a commonly used superior white pigment which exists in the form of a white powder. Is insoluble in water, and does not react with hydrogen sulfide or alkalis. Lithopone decomposes in acids with the release of hydrogen sulfide. Long-term exposure to sunlight causes lithopone to discolor, but putting it in a dark place will cause it to revert to its original color. It is used as a raw material for paints and paint pigments. Heating barium sulfate with a reducing agent will form barium sulfide (BaS), which is then reacted with zinc sulfate (ZnSO4) to yield a mixture of barium sulfate and zinc sulfide (70% BaSO4, 30% ZnS), which is referred to as lithopone. Barite used to make lithopone must have a BaSO4 content greater than 95%, and may not contain any visible, colored impurities.
