My YTZP (Yttria – Tetragonal Zirconia Polycrystalline) ceramic is a Yttria-Partially Stabilized Zirconia ceramic that is transformation toughened and it absorbs stresses that would shatter other ceramic materials. This is due to its martensite-type transformation mechanism of stress induction. Among the engineering ceramic materials, YTZP has some of the highest mechanical strengths and toughness at normal temperatures. It will go through phase transformation and slowly lose its properties at elevated temperatures (above 300 degrees C). It is relatively easy to be combined with metals because its coefficient of thermal expansion is close to that of metal.
