Product Description
Product Description:
White corundum is a type of abrasive material that is commonly used in many different applications. It is created by melting industrial alumina powder in an arc furnace at a temperature of over 2000 degrees Celsius, and then cooling it down. Once cooled, the material is ground and shaped, and then screened into different particle sizes using magnetic separation.
The unique properties of white corundum, such as its close texture, high hardness, and angular shape, make it well-suited for a variety of manufacturing processes. It is commonly used to make ceramics, resin consolidation abrasive tools, and for grinding, polishing, and sandblasting. It is also used in precision casting, where it is particularly useful as a special corundum for investment casting. Additionally, it can be used to create high-grade refractory materials.
The micro-powder grade of white corundum is ideal for wet sandblasting and grinding operations, as it has high processing speed and produces high-quality results. It is especially useful for sandblasting operations where there can be no iron residue, as the amount of iron oxide in white corundum is very low.
Features:
White corundum is a unique mineral that possesses a tripartite crystal system. In terms of physical properties, this mineral boasts impressive compressive strength at 2,000 MPa, tensile strength at 400 MPa, and flexural strength at 480 MPa. Additionally, this mineral has a thermal expansion coefficient of 8×10^-6 K^-1, thermal conductivity of 29 W/(m-K), and high temperature stability, which enables it to withstand extremely high temperatures.
Furthermore, white corundum has good resistivity of about 10^14 Ω-cm., optical properties such as transparency or translucency, and a refractive index of 1.76, with the default color being white, although it can also have light yellow, light blue, pink and other colors. Small amounts of impurities have relatively little effect on the properties of white corundum, which further adds to its versatility.
White corundum's hardness allows it to be used for surface polishing of glass, metal, and other materials, with the surface roughness going as low as 0.02µm. It has good corrosion resistance, making it ideal for use in chemical equipment and anti-corrosion equipment.
Additionally, white corundum has high wear resistance and thermal conductivity, making it an excellent material for abrasive manufacturing, abrasives, and even microelectronics.

Applications:
White corundum is a senior ceramic material widely used in many industries due to its high hardness, excellent wear resistance, and corrosion resistance. Its applications are as follows:
Abrasives
White corundum abrasives are mainly used to grind and polish metal parts, as well as to manufacture processing tools like knives.
Refractory Materials
The high temperature resistance and chemical stability of white corundum make it perfect for the manufacturing of refractory materials such as refractory bricks and plates, among others.
Thermal Barrier Coating
The white corundum powder is an excellent material for the manufacture of thermal barrier coatings. This coating is used to improve the efficiency and lifespan of high-temperature equipment such as engines.
Valves
White corundum valves work effectively for controlling various highly corrosive media in chemicals, petroleum, natural gas, and other industries due to their excellent corrosion resistance.
