Abstract
The invention is directed to cubic boron nitride (CBN) particles coated with a thin inner layer formed by the reaction of a reactive glass or ceramic to form a chemical bond and, optionally, an outer layer of a vitreous material. The particles are useful as abrasive particles in a vitreous bonding matrix. In addition, a method of preparing the particles and abrasive tools containing the particles are encompassed.
