The scanning electron microscope cathodoluminescence behavior of two partially stabilized zirconias is presented. Monoclinic material, either occurring on grain boundaries or produced by deformation, appears strongly luminescent, whereas in cubic‐plus‐tetragonal material grain boundaries appear dark, as do deformed regions associated with hardness indentations and wear tracks. These preliminary observations suggest that cathodoluminescence may be a valuable microstructural technique for characterizing the microstructure and deformation behavior of zirconia‐based ceramics.
