Abstract

In this study seven combination of Alumina and Zircon was selected by ratio of Alumina to Zircon of : 100/0, 85/15, 70/30, 45/55, 35/65, 20/80, 0/100. After weighing the powder raw material , mill for 24 hours and then were using press forming . The samples was sintered in temperatures of 1550 , 1600 , 1650 . To identify the phases and percentage of phases formed , X – ray diffraction pattern produced parts were investigated . The effect of Alumina to Zircon ratio and sintered temperature on the formation of mullite and zircon phases were investigated . All samples porosity were measured and the effect of combination and temperature and the final phases on this characteristic were studied .The results showed that zircon improved alumina sintered body of alumina and zircon are also accelerate decomposition .
