Abstract
One of the high-temperature metastable phases found in the MgGa2O4–Ga2O3 system is the εMg non-stoichiometric Mg gallate. It has a one-dimensional periodic antiphase boundary (PAPB) structure based on the spinel structure. The APBs are parallel to the {3 1 0} planes and the APB vectors are of the 1/4⟨1 1 0⟩ type when referred to the spinel structure. This generally leads to the existence of 12 monoclinic twin variants in the studied samples. By comparing the X-ray or electronic diffraction patterns of both phases, it will be shown that the recently discovered λ transition-alumina has the same type of structure.
