ABSTRACT:
A method of preparing preferred abrasive grain material is provided. The method involves steps of coating a non-sintered aluminum base particles with a metal alkoxide containing coating; heating to convert the coating to a metal oxide coating; and then sinter the base particles to provide sintered particles having an alpha-alumina-based core with an autogenously bonded metal oxide coating. The invention also concerns improved abrasive grain materials and abrasive products including the improved abrasive grain materials therein.
