1. In the glass and ceramic industries, barium carbonate is used as a roasting additive in the production of glass, which can improve its castable performance.After adding barium carbonate, the quality of the glass can be effectively improved, such as increasing the refractive index and hardness of the glass, and improving the performance and wear resistance of the glass.In optical special glasses, barium carbonate is a very important raw material for the production of barium oxide.The use of powdered barium carbonate in the manufacture of structural ceramics can improve the hardness, wear resistance and chemical corrosion properties of ceramic tiles.Adding barium carbonate to ceramics can reduce pores and air bubbles, improve the permeability of the product, and improve the coefficient of thermal expansion of the material.The use of barium as the glaze material can improve its roasting and wear resistance, firm color, bright and stable.

2. In re-industrial chemistry, it can be used as a chemical raw material for the production of chemical materials. Barium carbonate can be used to make sodium tripolyphosphate, and it can also be used in addition to sulfate in wet phosphoric acid; when preparing ferrate, its magnetism can be improved.In addition, it can also be used in barium chemicals such as barium nitrate and barium chloride, as well as pigments.
