Fine-dispersed powders of rare-earth elements (REE) aluminates were obtained by the "wet combustion" method. The solid-phase synthesis of lanthanum-gadolinium aluminate 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 rare-earth aluminates with low open porosity and relative density up to 99% of theoretical.
