Described is a fiber reinforced abrasive polishing and finishing tool comprising:

Fiber reinforced abrasive mold and die finishing tools

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.

Method of preparing abrasive articles

Abrasive greenware having improved strenght is prepared using a binder comprising poly(ethyloxazoline).
