| Abstract: | Zirconia （5wt. % Y2O3） and Alumina powder are used as theraw material, Zirconia/Alumina Ceramics composite was prepared successfully by gelcasty. Zeta potential, the granulairty distribution , theological behaviors of the Suspension and The microstructure of green bodies and sintered samples was measured and discussed . The result shown that the YSZ/Al2O3 composite ceramics, which is the 50Vol. suspension, was prepared at the pH value about 9-10, SD-00 as disperser which addition amount is 1. 0wt. %, and the optimum proportion is 70wt. %ZrO2（Swt. %Y2O3） and 30wt.% Al2O3. |
