With the help of model experiments carried out in the mode of linear heating of mixtures, which are promising refractory compositions: MCrO 4 + Mg + MgO and MCrO 4 + Al + Al 2 O 3 (M = Mg, Ca, Ba), the temperature regimes of the combustion reactions are determined. All processes of interaction of components were carried out using solid in-reaction oxidants - chromates of alkaline earth metals, which were also products of self-propagating high-temperature synthesis. The resulting refractories, in terms of their structural and physicochemical characteristics, are not inferior to products synthesized using conventional technology. Tab. 1, ill. 3, bibliography: 4 titles.
