| ABSTRACT Pure cordierite and cordierite - ZrO2 composites containing 10, 20 and 30 wt% Y2O3 stabilized ZrO2 have been prepared by dispersing ZrO2 powder in cordierite sol. The evolution of crystalline phases and the microstructure have been studied using X-ray diffraction and scanning electron microscopy. It was found that increasing both ZrO2 content and firing temperature enhanced the bodies' density. Mullite net and rods crystallize in the composite matrix when it heat treated at 1450°C. The beneficial effects of mullite and ZrO2 on the bending strength of the fabricated composites have been described. | ||||
