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

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

The thermodynamic functions of YbPO 4 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 YbPO 4 in the range 6–1800 K. The Gibbs energy of formati...

Zusammenfassung:The thermodynamic functions of YbPO 4 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 YbPO 4 in the range 6–1800 K. The Gibbs energy of formation of ytterbium orthophosphate (Δ f G 0 (298.15 K)) has been determined.
