Density, microstructure and microhardness have been investigated for samples, sintered from submicro-alpha-SiC and micro-SiC powders as well as their mixtures with addition of 50 vol.% alpha-Si3N4 nanopowder in the temperature interval 1500-2000 degrees C under pressure of 4 GPa. The dispersed silicon carbide submicron powder and the composite of submicro-SiC/nano-Si3N4 powder mixture have the most homogeneous microstructure and the higher hardness (respectively, up to 24 GPa and 22 GPa).
