Abstract
Vitrified bonded abrasive bodies prepared from sol-gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by coating the surfaces of the grit particles with a metal oxide, preferably by means of an organofunctional metal-containing surfactant having a metal content of at least about 10 weight percent.
