Electron spin resonance line widths for Cr 3+ and Fe 3+ were measured in α‐Al 2 O 3 samples doped with <1.2 mol% of Cr and Fe. Line width increased with increasing Cr and Fe concentration and decreased with increasing grain size. The experimental results show that this technique can be used to determine, rapidly and nondestructively, small concentrations of Cr and Fe in commercial Al 2 O 3 . Nomograms are provided to facilitate interpretation of the results.
