Inorganic Materials Aims and scope

Abstract

The heat capacities of lanthanum and lutetium orthovanadates have been measured at temperatures from 7 to 345 K using an adiabatic calorimeter. No anomalies have been detected in the heat capacity data. The thermodynamic functions (C 0 p (T), S 0(T), and H 0(T) − H 0(0)) of the two compounds have been calculated in the temperature range studied, and their Debye characteristic temperatures have been estimated.
