The defect structure of gamma-Al2O3, prepared by the thermal decomposition of well-crystallised, high purity boehmite (gamma-AlOOH), was studied by HREM. It is shown that the intrinsic feature of gamma-alumina structure is a presence of almost hexagonal closed loops formed due to the ordering of cat...
