High Temperature Calcined Treatment Brown Fused Alumina is calcined at the high temperature, and with the anneal treatment. Calcined with High Temperature Treatment Brown Fused Alumina is characterized by very low coefficient of linear expansion, very good hydrophilicity, good toughness and high hardness, producing the sintered grinding tools that is characterized by deep blue color after firing, without resillage, without rust and so on. So our this kind of product increase the precision and grinding ablity of the grinding tools in the using course.

The High-Temperature Calcined Brown Corundum is formed by high-temperature calcination of medium-temperature calcined abrasive during the production process of the original brown corundum, followed by high temperature calcination followed by bonfire treatment.

The main characteristics of High Temperature Calcined Treatment Brown Fused Alumina inclued this kind of Brown Fused Alumina is very small expansion coefficient, excellent hydrophilicity, great toughness, and high strength. The sintered abrasives produced have the characteristics of dark blue after burning, no network cracks and no rust. As a result, the accuracy and grinding effect of the grinding tools are improved, especially for the production of high-grade fixed abrasive tools.
