ABSTRACT:
There has been discovered the increased E-Modulus and grinding performance of vitreous bonded sol-gel abrasive grit abrasive articles, particularly abrasive grinding wheels, by the incorporation therein of inorganic, non-metallic bubbles. In a practice of the invention the abrasive article comprises a) an abrasive phase having sintered sol-gel alumina abrasive grits and second abrasive grits that are not of the sintered sol-gel type, b) a vitreous bond and c) essentially hollow, essentially spherical alumina particles having a softening temperature at least 50.degree. F. greater than the firing temperature of the vitreous bond.
