Description
The synthesis of dense sintered sialon with external additives selected from the system Y2O3-AlN-SiO2 is reported. The highest density (3.21 g/cm3) was achieved at 1750 degrees C at 90 min of sintering with 5 wt% additive. The degree of sialon substitution increased with the amount of liquid; the YSiO2N crystalline phase formed concurrently. Strength degradation occurred above 1000 degrees C. The fracture toughness of the material sintered with a lower amount of sintering aid remained relatively unchanged to 1200 degrees C. The material with more additive exhibited decreased toughness above 1000 degrees C
