Keywords:
molybdates of rare earth elements, X-ray powder diffraction, solid solution, limits of substitution, conductivityAbstract
The substitution neodymium for ytterbium in compounds Nd5Mo3O16 was investigated by X-ray diffraction. Solid solution Nd5-xYbxMo3O16 with cubic fluorite-related structure is formed in the composition rage up to x = 0,7. The substitution limit was determined by inflection of parameter a of cubic phase and by disappearing-phase method. It is near 3 at. %. The dependence of specific conductivity on composition is non-linear and has the minimum on x = 0,05.
