3. Product Application
The main uses of barium carbonate include the following aspects:
Electronics industry: Barium carbonate is used to manufacture various electronic components such as electronic ceramics, PTC thermistors, capacitors, etc.
Optics and Ceramic Industry: It is used in the manufacturing of optical glass, cathode ray tube glass, barium magnetic materials, etc., and is also used as an auxiliary material for ceramic coatings and optical glass.
Metallurgical industry: Barium carbonate is used for steel carburizing and metal surface treatment.
Other applications: It is also used to manufacture other barium salts, pigments, coatings, rubber, welding rods, etc., and can also be used as a water purifier and rodenticide.
4. Barium Carbonate Powder Used in Porcelain Glaze
1.Improving Whiteness and Glossiness: The high refractive index of barium carbonate enables the addition of barium carbonate to porcelain raw materials, effectively enhancing the whiteness and glossiness of ceramic products, resulting in a whiter and brighter appearance, fully satisfying people's pursuit of aesthetics.
2.Improving physical properties: The addition of barium carbonate can significantly improve the physical properties of porcelain, enhancing their hardness, wear resistance, and impact resistance, making ceramic products more durable and able to maintain excellent performance in complex and changing environments.
3.Adjusting the firing temperature: During the firing process of ceramics, barium carbonate decomposes to produce carbon dioxide and barium oxide. These decomposition products help reduce the temperature required for firing, thereby saving energy. Meanwhile, barium carbonate can also promote the sintering process of procelain, making the product denser and thus improving the overall quality.
4.Improving the texture of the glaze: Barium carbonate, as a component of the glaze, can improve the texture of the glaze, making it smoother and more delicate, and enhancing the adhesion and wear resistance of the glaze to the substrate. In addition, barium carbonate can also regulate the melting behavior and flowability of glazes, making the final formed glaze more uniform and aesthetically pleasing.
