METHOD OF MAKING CERAMIC SHAPED ABRASIVE PARTICLES SOL GEL COMPOSITION AND CERAMIC SHAPED ABRASIVE PARTICLES

摘要

A method includes: providing a mold having a plurality of mold cavities wherein each mold cavity is bounded by a plurality of faces joined along common edges; filling at least some of the mold cavities with a sol gel composition that includes a release agent dispersed therein; at least partially drying the sol gel composition thereby forming shaped ceramic precursor particles; calcining at least a portion of the shaped ceramic precursor particles to provide calcined shaped ceramic precursor particles; and sintering at least a portion of the calcined shaped ceramic precursor particles to provide ceramic shaped abrasive particles. A sol gel composition shaped ceramic precursor particles and ceramic shaped abrasive particles associated with practice of the method are also disclosed.
