Abstract
A method of coating ultrahard abrasive particles having vitreophilic surfaces, or treated to render their surfaces vitreophilic, are coated with an oxide precursor material, which is then heat treated to dry and purify the coats. The heat treated, coated ultrahard abrasive particles are further treated to convert the coats to an oxide, nitride, carbide, oxynitride, oxycarbide, or carbonitride thereof, or an elemental form thereof, or a glass.
