The preparation of dense ceramics based on magnesium aluminate spinel (AMS), a material with unique physicochemical properties, is considered. The work shows methods for producing AMS powders of stoichiometric composition by the method of reverse heterophase co-precipitation, studying the influence of the firing temperature and of the method of introducing of the sintering additive of gallium oxide on the ceramic properties of the obtained samples.
