摘要：
An in situ formed electroconductive beta-SiAlON/TiN ceramic composite was prepared by reactive sintering from Si + Al + + Al2O3 + TiO2 + Si3N4 + AlN powder mixture. The hear treatment, nitrogen pressure and starting powder composition were optimized and homogeneous ceramic material was prepared The reaction time was remarkably reduced by this method in comparison to the common liquid phase sintering route. The electrical resistivity of beta-SiAlON + 17 vol. % TiN composite was 2.7 . 10(-4) Omega m, confirming the suitability of this material for electrical discharge machining.
