This study compares the grain sizes of dense, equiaxed gadolinia (Gd 2 O 3 ) specimens as determined by light microscope/polished surface and by scanning electron microscope/fracture surface techniques. The average intercept lengths (AIL) as determined by the two techniques were found to differ only slightly. For Gd 2 O 3 in the grain‐size range studied, a factor of ∼1.10 converts the fracture‐surface AIL to the polished‐surface AIL.
