A method of preparing abrasive articles exhibiting improved homogeneity and breakdown properties is disclosed. The method comprises admixing abrasive grits and a bond phase comprising silica particles, alumina, a flux and water, to form a slurry, such that the silica particles are on the average smaller than the average grit particles; drying the slurry to form a precursor powder; and compacting the precursor powder to form an abrasive greenware article. This abrasive greenware article can then be densified, for example, by sintering, to form a densified abrasive article. The resulting abrasive article has a porcelain bond composition. Because of the uniform bond composition attained with this invention, extremely fine abrasive grits can be employed.
