Abstract:
A new method for the production of extremely wear-resistant aluminum oxide ceramic material, particularly Al2O3 in which at least 98% Al2O3 powder is mixed with 10-50 pph carbonaceous plasticizer, optionally pressed into a blank, heated to 1,280*1,500* C., sintered for at least 5 minutes at the highest temperature, and then cooled is described.

Abstract:
The surface of the carrier, e.g., steatite, is roughened or fissured by 1 layers of a granulate or granules, e.g., alumina. The carrier body is pref. ball-shaped, carrying one band, the thickness of the granulate layer being 1/5 - 1/100 pref. 1/10-1/20 of the ball dia.
