| 内容： | To provide a mixed ceramic which is based on Al2?3 and has a high wear resistance, low brittleness and chipping sensitivity, the invention proposes a mixed ceramic containing from 20 to 50% by weight of hard materials and from 0.01 to 5% by weight of ZrO2, wherein the hard materials are composed of metal carbides or metal carbonitrides and the Al2O3 particles do not exceed a mean particle size of 0.5 m and the hard material particles do not exceed a mean particle size of 0.4 m and the proportion of cerium oxide as sintering aid is from 0.05 to 1% by weight, with the base Al2O3 being able to contain a usual proportion of not more than 0.5% by weight of other sintering aids. |
