Production.Lithopone is produced by Coprecipitation of barium sulfate Barium sulfate (or sulfate) is an inorganic compound with chemical Formula BaSO4. It is a white crystalline solid, odorless and insoluble in water. It occurs in the form of the mineral barite, which is the main commercial source of barium and the materials for its preparation. https://en.wikipedia.org › wiki › barium sulfate

The most common co-precipitation is achieved by combining equimolar amounts of zinc sulfate and barium sulfide: BaS + ZnSO4 → ZnS · BaSO.
