Abstract

Using coprecipitation, we have synthesized LnVO4 (simple) and CaLnZr(VO4)3 (Ln = Nd, Sm, Eu, Gd, Dy, Yb) (ternary) lanthanide orthovanadates; a La0.3Nd0.5Sm0.1Eu0.1VO4 solid solution, modeling the composition of the lanthanides in radioactive waste (all crystallizing in the zircon structure, sp. gr. I41/amd); and LaVO4, crystallizing in the monazite structure. Their unit-cell parameters have been shown to increase systematically with increasing lanthanide ionic radius. Their mid- and far-IR vibrational spectra suggest that their symmetry is lower than that of classical zircon. The synthesized compounds are stable up to 900°C. Their average thermal expansion coefficients lie in the range (6–11) × 10–6 K–1.
