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.
