摘要
从晶体学和配位学的角度，结合电化学技术，讨论了氧空位对氧化锆相结构稳定性的影响及其在氧化锆四方相→单斜相转变过程中的作用。结果表明：氧空位的存在与变化不仅影响着氧化锆相结构的稳定性，而且影响着氧化锆的低温相变过程。对于含有一定量氧空位的亚稳四方相氧化锆，氧空位浓度的增加与减少都会进一步降低其结构稳定性。
Based on the crystallography of zirconia and the coordination of zirconium oxygen,and by means of electrochemical technique,the influence of oxygen vacancies on the stability of the phase structure and the phase transformation of zirconia was studied.It is found that the increase of oxygen vacancy content can increase the instability of the metastable tetragonal phase and accelerate the transformation to monoclinic zirconia.
