Abstract
n the present study, ZTA composites containing 0–10�vol% of 5mol% YSZ (in the range 0–10�vol%) were prepared by sol-gel technique followed by powder mixing and sintering up to 1650��C for 1�h. Microstructure of the composites was observed using scanning electron microscopy and phase compositions was detected by means of X-ray diffraction. Density increased and grain size decreased with the increase of zirconia content. Thermal diffusivity of the composites; determined at various temperatures up to 1400��C using laser flash technique; decreased with the increase of ZrO2content and temperature.
