SBM Solution On Barite Powder Production
② Lithopone pigment: heating barium sulfate, using a reducing agent to reduce to barium sulfide (BaS), and then reacting with zinc sulfate (ZnSO4) to obtain a mixture of barium sulfate and zinc sulfide (BaSO4 accounts for 70%, ZnS accounts for 30%) %) is the lithopone pigment. It can be used as a raw material for paints and painting pigments.
