The seeded transformation of boehmite‐derived alumina was studied by transmission electron microscopy. Crystallographic analysis confirmed that the growth of α‐Al2O3 on α‐Fe2O3 seed crystals occurs by solid‐phase epitaxy, with the orientation relationship [0001]Al2O3||[0001]Fe2O3 and [1120]Al2O3||[1120Fe2O3.
