High‐resolution transmission electron microscopy (HRTEM) was used to study the phase of orthorhombic ZrO 2 formed in magnesia partially stabilized zirconia (MgO‐PSZ) during HRTEM specimen preparation. Based on the three reported crystal structures of orthorhombic ZrO 2 , with the space groups Pbcm , Pbc 2 1 and Pbca , here it is shown that orthorhombic ZrO 2 formed in MgO‐PSZ has the Pbcm structure.
