Abstract

Foreliggende oppfinnelse angår partikler av hardt stoff på oksydbasis, spe- sielt av korund, og som er ommantlet med keramiske farvelegemer, samt en fremgangsmåte for fremstilling av disse partikler. Partiklene av hardt stoff ifolge oppfin- nelsen egner seg spesielt som farvegivende, slitasjeforminskende og/eller sklihemmende tilsetning til keramiske glasurer, eksempel- vis keramiske gulvfliser.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to oxide-based hard matter particles, especially of corundum, which are sheathed with ceramic dye bodies, and to a process for producing these particles. The particles of hard material according to the invention are particularly suitable as coloring, anti-wear and / or anti-slip additives to ceramic glazes, for example ceramic floor tiles.
