ABSTRACT:
A cost-effective process for polishing refractory materials, including natural and synthetic diamond, sapphire, ruby and Si.sub.3 N.sub.4 balls, is disclosed, wherein the surfaces thereof are successively softened to a predetermined depth by ion implantation, followed by mechanical polishing. This cycle of ion-implantation softening, followed by mechanical polishing, is repeated until such time that surface profilometry indicates that a desired surface smoothness has been achieved.
