= Yttria-stabilized zirconia
{wiki=Yttria-stabilized_zirconia}
Yttria-stabilized zirconia (YSZ) is a crystalline compound formed by the addition of yttrium oxide (Y2O3) to zirconium dioxide (ZrO2). This stabilization process is essential because zirconia can exist in different crystalline forms (phases), and at high temperatures, it can transform from its stable monoclinic form to a tetragonal or cubic form. However, this phase transformation can make pure zirconia brittle.
