✦ Synopsis

bsialon) nanopowders with the specific surface area of 60 -70 m 2 / g and average particle size of 30 -50 nm have been prepared by plasmachemical synthesis. By means of the hot pressing method at 1850 8C compact materials with fine-grained structure were prepared from this powders as well as from mixture of Si 3 N 4 -Al 2 O 3 -Y 2 O 3 with the second phase (10 wt.% SiC-Si 3 N 4 , ZrO 2 , TiN nanopowder). Addition of the second phase to silicon nitride improves material strength.
