ABSTRACT:
The present invention provides a nearly fully dense, microcrystalline, composite ceramic abrasive particle comprising grains of alumina, gamma-aluminum oxynitride and, optionally, a Periodic Group IVB metal nitride in the system Al.sub.2 O.sub.3 /ALON/Group IVB metal nitride. In another aspect, two different processes for making an abrasive particle such as an abrasive grit, comprising a multiphase mixture of microcrystalline components in this system using sol gel techniques and pressureless reaction-sintering, are disclosed.
