Notes:
Phase relations and lattice constants in the MgO–Al2O3–Ga2O3 system at 1550°C have been determined experimentally. In a large part of this system, only a nonstoichiometric spinel is stable. Compositions as extreme as 12.5 mol% MgO–20.5 mol% Ga2O3–67 mol% Al2O3 for a homogeneous spinel are possible. In the bordering phase diagrams of MgO–Al2O3 and MgO–Ga2O3, the composition of the spinel is as high as 63 mol% Al2O3 or Ga2O3, respectively. The contributions of all simple ionic exchange reactions on the lattice constant of the spinel have been deduced from X-ray diffractometry data.
