1. Introduction
This kind of brown fused alumina grain is calcined at the medium high temperature, and with the anneal treatment. It is characterized by very low coefficient of linear expansion, very good hydrophilicity, good toughness and high hardness, producing the sintered grinding tool that is characterized by deep blue color after firing, without resillage, without rust and so on. So this kind of product increases the precision and grinding ability of the grinding tools in the using course. Brown fused alumina with the medium high temperature treatment is applicable to make high quality bonded abrasives.
