摘要
Powder mixtures based on Si3N4 nanoparticles and yttrium and aluminum oxides were prepared. Ceramic samples with a relative density of 95-96% have been produced by spark plasma sintering at a pressure of 80 MPa and a heating rate of 50 degrees C/min. The microstructure of the samples has been shown to be formed by Si2N2O grains similar to 0.7 mu m in size, with an amorphous oxide phase in between. The highest hardness (13.3 GPa) was reached by the sample containing the Y2O3 and Al2O3 oxides in the molar ratio 2 : 1 and obtained at a sintering temperature of 1770 degrees C.
