Abstract: PURPOSE:To make it possible to obtain a polished surface with no scratches, by forming an ultra-precise polishing abrasive material from spherical ultramicro particle-like beta type polycrystal silicon carbide having an averaged particle size of 0.01 to 1mum, which is the aggregate of beta type silicon carbide of crystallite of less than 50 angstroms. CONSTITUTION:An ultra-precise polishing abrasive material is formed of a spherical ultramicro particle-like beta type polycrystal silicon carbide having an averaged particle size of 0.01 to 1mum, which is the aggregate of beta type silicon carbide having crystallite of less than 50 angstroms. Such ultramicro particle-like betatype polycrystal silicon carbide may by obtained from organic silicon corbide in which at lease one of identical SiH bond exists in a molecule but no SiX (X is halogen atom or oxygen atom) bond exists, or the like, which is subjected to a vapor phase cracking process at a temperature above 50 deg.
