Microctystalline fused alumina is a new type of abrasive product developed by our plant to meet the domestic and international market in recent years. It is a derivative species of brown fused alumina, and its appearance, color and chemical composition are similar to brown fused alumina. 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.
