Investigation of the Properties of Alumina-Zirconia Ceramics Alexandr S.
Alumina-zirconia ceramics due to its unique property to resist the spreading of microcracks because of the phase transitions under load belongs to the category of instrumental (structural) ceramics with mechanical properties being the primary ones.
Another feature of alumina-zirconia ceramics is its large anionic conductivity at high temperatures, which allows attributing this ceramic material to superionic conductors widely applied in power engineering.
