在500℃下对氧化钙稳定的氧化锆多晶(CSY)和氧化钇稳定的氧化锆单晶体(YSZ)进行了电化学还原，采用玻璃包覆的方法防止分子氧从气相中进入，并实现了反应晶体的几乎二维几何形状。通过光学显微镜在加热阶段原位观察到了由形态不稳定的反应前沿推进而产生的发黑过程。(C)1999由爱思唯尔科学公司出版。版权所有。
Electrochemical reduction was performed on both polycrystals of calcia-stabilized zirconia (CSY) and single crystals of yttria-stabilized zirconia (YSZ) at 500 degrees C. A glass-encapsulation was used to prevent access of molecular oxygen from the gas phase and to realize a virtually two-dimensional geometry for the reacting crystal. The resulting blackening process which occurs by the advancement of a morphologically unstable reaction front was observed in-situ in a heating-stage by the use of an optical microscope.
