The nanopowders (Si3N4, AlN, Al2O3, Y2O3 and Si3N4-27 wt.% AlN nanocomposite) were produced by the plasmachemical synthesis. The composite materials were sintered by the method of pressure-less sintering. Sintering temperature decreased significantly, if Si3N4-AlN nanocomposite was used as one of the components. The increased amount of a- sialon phase and higher hardness are characteristic for materials obtained from separate Si3N4, AlN, Al2O3, Y2O3 nanocomponents.
