Summary

High qualify Si3V4 powder developed by the method of the thermal decomposition of Si(NH)2 was characterized and its sintering behavior was studied. Densification studies indicated that the highly pure, fine Si3V4 powder with a narrow particle-size distribution was sinter-active and dense β-sialon-alloys were produced by reaction sintering of the highly pure, sinterable Si3N4 Al2O3, AIN, and Y2O3. High temperature strength was improved by the reduction of excess oxygen in the sialon system.
