Precipitation of Mg2Zr5O12 in MgO‐Partially‐Stabilized ZrO2

Abstract
Decomposition of cubic, MgO‐stabilized ZrO2 solid solutions has been studied. Precipitates of the ordered compound, Mg2Zr5O12, form, but only when a two‐stage heat treatment involving nucleation at a low temperature followed by growth at a higher temperature is used. Other decomposition products are also present after such a heat treatment.
