ABSTRACT:
Improved ceramic tool compositions comprising primarily aluminum oxide are provided. The aluminum oxide can be supplemented with other oxides including zirconium oxide, magnesium oxide, hafnium oxide. In addition are added silicon nitride or aluminum nitride together with dispersed particles comprising carbides, nitrides and/or carbonitrides. These compositions are prepared by e.g., a reaction hot pressing process and ceramic bodies prepared in accordance with the invention display superior wear resistance to conventional tool compositions.
