Mechanism of Liquid-Phase Sintering of Silicon Carbide and Nitride with Oxide Activating Additives

The mechanism of sintering and the particulars of structure formation in liquid-phase-sintered silicon carbide and sintered silicon nitride were studied. The formation of the structure core (SiC or Si3Ni4 grains) – boundary layer (SiC oxide or SiAlON) – intergrain phase (oxides) was recorded.
