Abstract

See full text

Abrasive grain, corundum (Al.sub.2 O.sub.3) comprising titanium oxide, preferably Ti.sub.2 O.sub.3, is provided with a ceramic coating. The abrasive grain is subjected to a heat treatment whereby the Ti-oxides change from the trivalent into the quadrivalent degree of oxidation. The coating and the change of the degree of oxidation are effected simultaneously.
