摘要：A method of making sintered abrasive particles includes passing aluminaprecursor particles through a flame under conditions such that they are converted toalpha alumina. The precursor particles comprise a precursor of alpha alumina and have anaverage particle size of less than or equal to 500 microns. Sintered abrasive particles havea cellular microstructure comprising alpha alumina crystal grains of alpha alumina havinga maximum dimension of less than about 3 microns are also disclosed. The sinteredabrasive particles have an average particle size of less than or equal to 500 microns, andare essentially free of seed particles and alpha alumina grain size modifiers. Abrasivearticles comprising a binder and a plurality of the sintered abrasive particles are alsodisclosed.
