Abstract
Nano-sized Si3N4 powder coated with Y2O3 and Al2O3 sintering additives has been sintered by hot pressing and gas pressure sintering at reasonably low temperature. Remarkable influence of used sintering method and heat-treatment regimes on the microstructure was observed. Vickers hardness and fracture toughness was measured by indentation testing method. Correlation between obtained microstructures and mechanical properties was observed.

Key words
ceramics, nitrides, sintering, hardness, toughness
