Microctystalline fused alumina is made by changing crystal cooling method. Its crystal size is small (50--280um), and its grain is combined from fine crystal polymerization, with the features of good toughness, high intensity and good self-sharpening. Abrasive tools which is produced by Microctystalline fused alumina is suitable for grinding stainless steel, carbon steel,ball milling cast iron etc, and its grinding way can be applied in form grinding, infeed grinding, precision grinding and heavy-burdened grinding.
