Some results were obtained that adulterating zirconia with yttria , viz . yttria - stabilized zirconia ( ysz ) , has some oxygen ion vacancies , sequentially has ionic conductivity . and the influence on ysz ion conductivity of the different adulterated concentration of yttria was discussed 以溶胶-凝胶( sol - gel )理论为基础,制备钇稳定立方相二氧化锆( ysz )溶胶-凝胶膜,并对不同的药品配比进行测试与比较。
