Structure and Positron Characteristics of Basic Open Volume Defects in Zirconia

摘要：

Zirconia (ZrO2) based materials are promising for many practical applications, including heat-resistance structural and functional ceramics, solid oxide fuel cells, oxygen sensors, as well as applications in nuclear fuel and waste confinement. For such applications it is often necessary to employ the cubic zirconia phase that can be stabilized at ambient temperature by adding yttria (hence yttria stabilized zirconia (YSZ)). Due to such doping oxygen vacancies are present in YSZ in a large amount. An aggregation of oxygen vacancies was also detected experimentally and confirmed by simulations. Nevertheless, the role of point defects in YSZ is yet far from being understood.
