Shaped abrasive particles, methods of making, and abrasive articles including the same

A method of making shaped abrasive particles, the method comprising:

• providing a slurry comprising non-colloidal solid particles and a liquid vehicle, wherein at least some of the non-colloidal solid particles comprise aluminum oxide powder, and wherein the non-colloidal solid particles comprise at least 30 percent by volume of the slurry;
• forming at least a portion of the slurry into shaped bodies contacting a substrate, wherein the shaped bodies are formed substantially according to a predetermined shape;
• at least partially drying the shaped bodies to provide shaped abrasive precursor particles;
• separating at least a portion of the shaped abrasive precursor particles from the substrate;
• and
• converting at least a portion of the shaped abrasive precursor particles into shaped abrasive particles, wherein the shaped abrasive particles comprise alpha alumina having an average crystal grain size of 2.7 to 8 microns and an apparent density that is at least 92 percent of the true density, and wherein the shaped abrasive particles contain 0.03 to 0.08 percent of sodium oxide based on the total weight of the shaped abrasive particles.
