摘要
选用ZrO2（5wt．％Y2O2）和Al2O2为粉体原料，采用溶胶凝胶法制备氧化锆基氧化铝（YSZ／Al2O3）复合陶瓷，研究了悬浮体的Zeta电位、分散性、流变性及其显微结构．结果表明：在pH=9～10附近、选用SD-00为分散剂，加入量为1．0wt．％，粉体最佳配比为70wt．％ZrO2（5wt．％Y2O2）和30wt．％Al2O3获得固相含量为50Vol．％的悬浮体，制备出了均匀致密、高强度的YSZ／Al2O3复合陶瓷．
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.
