Abstract
The crystal structures and ionic conductivity of yttria stabilized zirconia(YSZ) are analyzed.Out of the type of transition of oxygen vacancies in YSZ,the reason that the conductivity of YSZ emerges a maximum as dopant increases are discussed.The activating energy of oxygen ion reduces and the probability of transition increases ,and the conductivity increase also progressively with the increase of temperature.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
