Title: Enthalpies of Formation of Rare-Earth Orthovanadates, REVO 4

Abstract

Rare earth orthovanadates, REVO4, having the zircon structure, form a series of materials interesting for magnetic, optical, sensor, and electronic applications. Enthalpies of formation of REVO4 compounds (RE=Sc, Y, Ce Nd, Sm Tm, Lu) were determined by oxide melt solution calorimetry in lead borate (2PbO {center_dot} 2B2O3) solvent at 1075 K. The enthalpies of formation from oxide components become more negative with increasing RE ionic radius. This trend is similar to that obtained for the rare earth phosphates.
