Product Description
Product Description:
White corundum is a type of abrasive material that is widely used in various industries. It is produced by melting industrial alumina powder in an arc furnace at a temperature of more than 2000 degrees and then cooling it. The resulting material is ground and shaped, and magnetic separation of iron is done to screen particles of different sizes for different products.
The texture of white corundum is very close, and its angular shape and high hardness make it suitable for a variety of manufacturing applications. It is commonly used in the production of ceramics, resin consolidation abrasive tools, precision casting (investment casting special corundum), high-grade refractory materials, and for grinding, polishing, and sandblasting.
The micro-powder grade of white corundum is ideal for wet sandblasting and grinding operations, with high processing speed and high quality. The amount of iron oxide is very low, making it suitable for sandblasting operations with no iron residue.
Features:
Crystal Structure
White corundum has a tripartite crystal system.
Mechanical Properties
White corundum has a high compressive strength of 2,000 MPa, a tensile strength of 400 MPa, and a flexural strength of 480 MPa, making it a highly durable material.
Thermal Properties
White corundum has a low thermal expansion coefficient of 8×10^-6 K^-1, a thermal conductivity of 29 W/(m-K), and high temperature stability, allowing it to withstand extremely high temperatures. It also has good thermal conductivity, making it popular in the field of microelectronics.
Electrical Properties
The resistivity of white corundum is about 10^14 Ω-cm.
