Liquid-Phase Sintering of Chemically Unstable Silicon-Carbide Lithium/Magnesium Aluminosilicate Titania Composites
The fully dense 55 wt% SiC-45 wt% (LAS/MAS/TiO2) composite consisting of SiC filler particles and glassy matrix has been prepared by liquid-phase sintering in the presence of carbon, using the heating rate of 800 degrees C min(-1), the maximum sintering temperature 1600 degrees C and the nitrogen overpressure of 8 x 10(-5) Pa applied at a maximum particle mobility stage. The total liquid-phase sintering time did not exceed 4 min. The bloating effect was always observed in the carbon-free atmosphere during liquid-phase sintering.
