Abstract: A method of making shaped abrasive particles including forming an abrasive flake comprising a plurality of precursor shaped abrasive particles and a frangible support joining the precursor shaped abrasive particles together; transporting the abrasive flake through a rotary kiln to sinter the abrasive flake; and breaking the sintered abrasive flake into individual shaped abrasive particles. The method is useful to make small shaped abrasive particles having insufficient mass to be efficiently individually sintered in a rotary kiln without joining two or more of the shaped abrasive particles together.

Abstract: 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.
