Ceramic glazes

Precipitated barium sulfate is produced by calcining barite with coal to generate sulfate, which is then reacted with glauber's salt to obtain precipitated barium sulfate and by-product sodium sulfate. The sulfate process involves the reaction of barium sulfide with carbon dioxide to form sulfate. Precipitated barium sulfate can be added to ceramic materials and is converted to barium oxide during melting, which enhances the hardness and luster of the glaze, thereby improving its wear resistance. Barium carbonate added to enamel can also improve its corrosion resistance and resistance to weathering. Barite is an important filler and additive in non-drilling industries. The ceramic industry is a traditional major market for precipitated barium sulfate, used in the production of lubricant additives, polyvinyl chloride stabilizers, and as a substitute for barium carbonate to fix sol salts in the ceramic industry.
