Fine-dispersed powders of REE ferrites were obtained by the "wet combustion" method. The solid-phase synthesis of lanthanum-gadolinium ferrite has been studied. It has been shown that the target phase can be obtained at temperatures up to 750 ° C. Firing modes have been found that make it possible to obtain ceramics based on REE ferrites with low open porosity and relative density up to 99% of theoretical. Tab. 2, ill. 3., bibliography: 4 titles.
