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 Ceramic Tiles
1. Improving density and hardness: Adding an appropriate amount of barium carbonate can increase the density and hardness of ceramic tile raw materials, thereby improving the physical properties of the product, making the tiles more solid, wear-resistant, and having better compressive, bending, and impact resistance.
2. Enhanced fire resistance: At high temperatures, barium carbonate can react with other minerals to form stable compounds, enhancing the fire resistance of ceramic tiles. For example, barium carbonate can react with silicon oxide to form stable barium silicate, which has a melting point of over 1600 ℃ and can effectively improve the high temperature resistance of ceramic tiles.
3. Improving sintering performance: Barium carbonate can be used as a coloring agent for porcelain glazes and ceramics. Adding it to porcelain tile glazes can improve the coloring effect of glazes and promote the sintering process in ceramic technology. The addition of barium carbonate can also improve the sintering performance of raw materials, promote the bonding between mineral particles, accelerate the sintering of glazes and minerals, and improve process efficiency.
4. Improving Whiteness and Glossiness: The high refractive index of barium carbonate allows the addition of barium carbonate to ceramic tile raw materials to effectively enhance the whiteness and glossiness of tiles, presenting a whiter and brighter appearance and meeting people's pursuit of aesthetics.
