The mechanism of YSZ

    Hi
    I wanted to know what is the exact mechanism of stabilizing Zirconia (cubic phase) by Yttria
    thanks
    :confused:

    Here is one proposal for the mechanism and is generally consistent with my understanding.

    Ref: Stefano Fabris, Anthony T. Paxton and Michael W. Finnis,
    A stabilization mechanism of zirconia based on oxygen vacancies only
    Acta Materialia, Volume 50, Issue 20, 3 December 2002, Pages 5171-5178

    The behavior the RE-sesquioxides in transitional metal oxides and actinide oxides is of interest.

    Hi,
    please help to understand me why in the synthesis of stabilized Zirconia(YSZ, CSZ....etc ) by any solid state route or hydrothermal processing.......... high tempreature need for phase formation ?
