The processes at high temperature annealing of non-stoichiometric МgО·nАІ₂O₃ spinel crystals (n = 2.2) in O₂ atmosphere at 1300-1500°C have been investigated. A gradual non-stoichiometry increase up to n = 2.8 has been found with increasing annealing time due to MgO evaporation followed by formation...
