THE EFFECTS OF SILICA SAND (Si02) AND ZIRCONIA (Zr02) ON THE MECHANICAL AND THERMAL PROPERTIES OF THE PRESSURELESS SINTERED Al203-Si02-Zr02 COMPOSITE

The research work presents an investigation on the pressureless sintering, microstructure and mechanical properties of three component ceramic composite material consisting of alumina, silica and zirconia for structural applications. The effect of each component composition on the physical and me...
