Abstract: Liquid phase sintering of Si3N4 with melts from the system Ce2O3-AIN-SiO2 has been studied. The glass forming region in this system and the reaction products formed during sintering at 1750-1800°C were analysed. Sintering of SigN4 with two melt compositions selected from outside the glass forming region yields fully dense Si3N 4. Post sintering treatment at 1300°C resulted in devitrification with consequent improvement of high temperature mechanical properties. The mechanical properties of Si3N4 sintered with liquids in the system Ce2O3-AIN-SiO2 were found to be inferior to those of liquids selected from Y2O3-AIN-SiO2, but superior to those selected from the system MgO-AIN-SiO2.
