Application of Brown Corundum in Ceramics
I. Ceramic Coatings
Improve Hardness and Wear Resistance
The high hardness of brown corundum makes it an ideal additive for ceramic coatings. It can significantly reduce the loss of coatings in friction or wear environments, extend the service life, and is suitable for high wear scenarios such as mechanical equipment and automotive parts.
Enhance Chemical Stability
Ceramic coatings with brown corundum can effectively resist chemical corrosion such as acid and alkali, and are suitable for corrosive environments such as chemical equipment and marine facilities.
High Temperature Resistance
Brown corundum remains stable at high temperatures, making the coating suitable for high temperature working environments such as kilns and furnaces, avoiding deformation or failure of the coating.
Improve Coating Bonding
By optimizing the formula and process, brown corundum can enhance the adhesion of the coating to the substrate (such as metal or ceramic substrate) and reduce the risk of falling off.
II. Ceramic Glazes and Pigments
Glaze Performance Optimization
Brown corundum micropowder is used in ceramic glazes to improve the wear resistance and gloss of the glaze, while enhancing color stability and improving the aesthetics of the product. Pigment additives
The particle size is controllable, and the glaze texture can be adjusted to form a uniform and delicate surface effect.
Ⅲ. Ceramic structural materials
High-temperature kiln linings
Brown corundum castables are used to manufacture refractory linings for ceramic kilns and glass melting furnaces. They are resistant to high temperatures of more than 1600°C and can resist the erosion of molten glass or ceramic raw materials.
Saggers and kiln tools
During the ceramic firing process, brown corundum materials can be used to make saggers, kiln car linings and other components to withstand repeated high-temperature impacts and extend the life of the equipment.
Ⅳ. Modified ceramic materials
Physical modification
The particle size and surface roughness of brown corundum are adjusted through processes such as ball milling and screening to enhance the hardness and compressive strength of the ceramic matrix.
Chemical modification
Surface treatment or chemical vapor deposition technology can improve the corrosion resistance and thermal stability of brown corundum, making it more suitable for the preparation of high-performance ceramics.
Ⅴ. Other Applications
Sandblasting and Surface Treatment
Brown corundum powder is used for sandblasting of ceramic surfaces to enhance substrate cleanliness and coating adhesion.
Electronic ceramic packaging
In the field of electronic ceramics, brown corundum can be used as a filler to improve the thermal conductivity and mechanical strength of the material.
Summary
Brown corundum is widely used in ceramic coatings, glazes, high-temperature structural parts and modified materials due to its high hardness, wear resistance, high temperature resistance and chemical stability, which significantly improves the performance and application range of ceramic products, especially in the fields of high-temperature industry, machinery manufacturing and fine ceramics.
