Used as a material or filler for paints, inks, plastics, advertising pigments, cosmetics, and storage batteries. It is used as a filler and reinforcement in rubber products. It is used as a filler and weighting agent in polyvinyl chloride resin for printing. Surface coating agent for paper and art paper, sizing agent for textile industry. Glass products are used as clarifiers, which can defoam and add gloss. It can be used as a protective wall material for anti-radiation. It is also used in ceramics, enamels, spices and paints. It is also a raw material for the manufacture of other barium salts-powder coatings, paints, marine primers, ordnance paints, automotive paints, latex paints, interior and exterior wall building coatings, which can improve the product's light resistance, weather resistance, chemical and electrochemical corrosion resistance and products The decoration function enhances the impact resistance of the coating. In the inorganic industry, it is used as a material for manufacturing other barium salts such as barium hydroxide, barium carbonate, and barium chloride. It is used to make primer and modulate printing paint when wood grain printing plate is produced in the wood industry. In organic synthesis, it is used as green pigment and lake to produce physique filler.

Printing-Ink filler, can play the role of anti-aging, anti-exposure, add adhesion, clear color, bright and non-fading.

Filling-tire rubber, insulating rubber, rubber sheet, tape, engineering plastics can enhance the anti-aging function and weather resistance of the product, the product is not easy to age and become brittle, and can significantly improve the surface finish and reduce the manufacturing cost. It is used as a powder coating The main filler is the main method to adjust the bulk density of the powder to increase the powdering rate.

Functional materials-paper-making materials (mainly paste products), flame-retardant materials, anti-X-ray materials, battery cathode materials, etc. Both can show common functions and are an indispensable and important part of related materials.

Other areas-ceramics, glass materials, special resin mold materials, the combination of deposited barium sulfate with special particle size and titanium dioxide, has a synergistic effect on titanium dioxide, thereby reducing the amount of titanium dioxide.

How to produce deposited barium sulfate and barium ions will generate barium carbonate deposits. There is a balance between barium ions and carbonate in water. If there is barium sulfate deposits in water, there will be a balance between sulfate and barium ions. The two equilibriums will interact, even though the solubility of barium sulfate is less than that of barium carbonate.

However, because carbonate and barium ions generate barium carbonate deposits, the barium sulfate deposits and dissolution balance will move and part of the barium sulfate will be re-dissolved in the water, so that the sulfate radicals cannot be removed, so we must first filter out the barium sulfate Sodium carbonate can be added. Mix the barium sulfide solution with the Glauber's salt solution after removing the calcium and magnesium, and react at 80°C to form deposits. After suction filtration, water washing and acid washing, adjust the pH to 5-6, and then Filtered, dried and crushed. Barium yellow halogen can also be used to react with Glauber's salt solution to prepare deposited barium sulfate.
