The Rare Earth

A method of analysis is proposed which utilizes thecharacteristic melting points of the hydrated salts andthe liquidus curves of the binary salt mixtures for theestimation of the composition of rare earth mixtures.Several binary salt systems were investigated, employingvery pure simple and double rare earth nitrates toprovide basic information concerning the possibilitiesof the method.

Character of influence of the strontium atoms replacement by smaller atoms of calcium on structure features of the Ruddlesden-Popper (Sr,Ca)LaScO4 (A2BO4) single-slab compoundis established. Structure of phase with a maximum degree of replacementhas determined by the Rietveld method. It is shown that such type of substitution increases a degree of AO9 interblock polyhedra deformation, mutual inclination of the BO6 octahedra and a decrease of A - О interblock bond. Presence of structure changes is the precondition for regulation of structural-dependent features of the materials on the base of scandates alkaline-earth and rare earth metals.
