Reactivity in the solid-state between ZnWO4 and some rare-earth metal molybdates RE2MoO6 (RE=Y, Sm, Eu, Gd, Dy, Ho, Er and Lu)

摘要

Reactivity in the solid-state between ZnWO4 and some RE2MoO6 (RE=Y, Sm, Eu, Gd, Dy, Ho, Er and Lu) was investigated by XRD and DTA-TG methods. Four new compounds with the formula ZnRE2MoWO10 (RE=Sm, Eu, Gd, Dy) were synthesized. The obtained compounds are isostructural and crystallize in the monoclinic system. They melt incongruently within the temperature range of 1016–1033°C. The solid product of melting is an adequate of rare-earths molybdate.
