Abstract
A method of forming an abrasive article includes forming a mixture comprising a liquid carrier and a glass precursor material, wherein the glass precursor material comprises a material selected from the group of materials consisting of a hydrated metal compound, an organic silicate compound, or a combination thereof. The method further includes providing abrasive grains within the mixture, forming the mixture into a green ceramic body, and heating the green ceramic body to form a bonded abrasive article comprising the abrasive grains contained within a bond matrix, wherein the bond matrix comprises an amorphous phase formed from the glass precursor material.
