Product Description
Product Description:
White corundum is a type of material that is derived from industrial alumina powder. The process for creating it involves melting the powder in an arc furnace at a high temperature, exceeding 2000 degrees. After the material is cooled, it is ground, shaped, and screened for particle size to create different products. Due to its angular shape and close texture, it is ideal for manufacturing ceramics, resin consolidation abrasive tools, precision casting, and high-grade refractory materials.
Compared to brown corundum, white corundum has a slightly higher hardness and a slightly lower toughness. This material is highly pure, self-sharpens, and has strong grinding ability, making it efficient and effective for various applications. Additionally, white corundum is acid and alkali-resistant, has high thermal stability at elevated temperatures, and does not affect the color of the workpiece. It is also suitable for sandblasting in the process where iron powder residue is prohibited, due to its low iron oxide content.
The micro-powder grade of white corundum is highly suitable for wet sandblasting and grinding operations due to its high processing speed and quality. It is also ideal for sandblasting operations where no iron residue is permitted.
Features:
White corundum is a highly versatile material that offers a range of physical and chemical properties suited to a variety of industrial applications. Among its key characteristics is its tripartite crystal system, which gives the material its unique look and feel. Additionally, white corundum has a high compressive strength of 2,000 MPa, which makes it well-suited to high-stress applications.
In addition to its compressive strength, white corundum also boasts a tensile strength of 400 MPa and a flexural strength of 480 MPa. These properties make it highly durable and resistant to wear and tear, making it ideal for use in abrasive materials and abrasives. The material also has a thermal expansion coefficient of 8×10^-6 K^-1 and a thermal conductivity of 29 W/(m-K), lending itself well to use in high-temperature environments.
Because of its high temperature stability, white corundum is able to withstand even the most extreme conditions and is highly resistant to corrosion. Additionally, it has a high resistivity of approximately 10^14 Ω-cm and is transparent or translucent, with a refractive index of 1.76. The material is typically white in color, though it may also feature other light colors such as yellow, blue, or pink.
