A method of obtaining a chemically stable matrix based on aluminate perovskite for immobilization of the actinide fraction of radioactive waste by means of self-propagating high-temperature synthesis is examined. The basic parameters of synthesis as well as the conditions of preparation for the initial batch of the components influencing the phase formation process in the final matrix are described. The leach rate of the actinide simulator from the obtained perovskite-based matrix material is in line with the IAEA MSS-1 test.
