On the magnetic diagnostics of the process of self-propagating high-temperature synthesis of ferrites

Process of phase formation of ferrites in systems of Li-Fe-O type was investigated according to their spontaneous magnetization during synthesis under burning conditions. Magnetization of burning sample in lithium orthoferrite system grows monotonously with time and posses through the maximum during cooling and through the minimum in lithium ferrite system. The difference in dependence of magnetization on time is explained by the fact that burning temperature of lithium orthoferrite is lower, than curie point both for initial materials and for final product
