The Calcined with Medium High Temperature Treatment Brown Fused Alumina is calcined at a high temperature of 1050°C during the production process of the raw brown corundum, and then subjected to a bonfire treatment.

The Calcined with Medium High Temperature Treatment Brown Fused Alumina has the characteristics of very small expansion coefficient, excellent hydrophilicity, high toughness, and high strength, etc. The sintered abrasive tool produced has the characteristics of dark blue, no mesh crack, and no rust spot after firing. Improve the precision and grinding effect of grinding tools, especially for the production of high-grade fixed abrasive tools.
