The white corundum is.uses industrial aluminum oxide powder as raw material and undergoes melting at temperatures above 2000 degrees Celsius in an electric arc. The scorching high temperature melts the aluminum oxide powder into a new form, which is then processed through a series of fine processing steps such as cooling, crushing and shaping, magnetic separation to remove iron, and screening. Finally, it is made into products of various particle sizes. Its texture is dense, its hardness is extremely high, and its particle shape presents a unique pointed shape, which lays a solid foundation for its outstanding performance in different fields.

2 . The application of white corundum
Hardness is one of the most prominent characteristics of white corundum. Its Mohs hardness is as high as 9.0, Rockwell hardness is 46HRC, and Vickers hardness HV is between 2100-2300kg/mm ². Such high hardness makes white corundum play an irreplaceable role in the fields of grinding and cutting. White corundum can easily handle materials with high hardness and tensile strength, such as quenched steel, alloy steel, high-speed steel, and high carbon steel, and efficiently process them, greatly improving production efficiency and product quality.
In the precision casting industry, white corundum also excels. Due to its high fire resistance and excellent chemical stability, it can withstand the high temperature environment during the casting process and will not undergo chemical reactions with other substances at high temperatures, thereby ensuring the quality and accuracy of the castings. The use of white corundum as a mold material enables the production of high-quality castings with minimal defects, providing strong support for the development of the precision casting industry.
White corundum is also an indispensable and important material in surface treatment processes. For example, in sandblasting and shot peening processes, white corundum can effectively remove pollutants from various material surfaces, such as oxide layers and carbide black scales on metal surfaces, as well as rust on non-metallic surfaces. After sandblasting treatment with white corundum, the surface not only has high cleanliness, but also suitable roughness, which can significantly improve the adhesion of subsequent coatings or paints, greatly improving the appearance quality and durability of the product.
White corundum is also widely used in the manufacture of advanced refractory materials. In high-temperature industrial environments, such as furnaces, kilns, and other equipment, it is necessary to use materials that can withstand high temperatures and have good insulation performance to ensure the normal operation and production safety of the equipment. White corundum has become a key component in the production of refractory materials due to its high refractoriness and low thermal conductivity. The refractory material made of white corundum can provide reliable insulation and heat protection for high-temperature equipment, extend the service life of equipment, and reduce production costs.
