Heat capacity and thermodynamic functions of YbPO4 from 0 to 1800 K

  • Published:
Inorganic Materials Aims and scope

Abstract

The thermodynamic functions of YbPO4 have been determined experimentally in the temperature range 6–1745 K. The results have been used to calculate temperature-dependent heat capacity, entropy, enthalpy increment, and reduced Gibbs energy of YbPO4 in the range 6–1800 K. The Gibbs energy of formation of ytterbium orthophosphate (Δf G 0(298.15 K)) has been determined.
