| Abstract: | The growth of α-Al2O3 from a planar specimen of thermally grown γ-alumina on a molybdenum transmission electron microscope grid was studied. The α-Al2O3 grows into the transition alumina matrix and then thickens via a ledge growth mechanism. Faceted Mo crystallites cause pinning of α-Al2O3 ledges and are larger on α-Al2O3 than on the transition alumina matrix. |
