Publication date: Available online 11 November 2019Source: Thermochimica ActaAuthor(s): A.V. Tyurin, M.A. Ryumin, A.V. Khoroshilov, V.M. Gurevich, K.S. GavrichevAbstractThe heat capacity of holmium orthophosphate HoPO4 was studied using an adiabatic and a differential scanning calorimetry in the temperatures intervals 9–338 and 310–1374 K, relatively. Heat capacity anomaly connected with the splitting of ground state electronic levels of f-shell was determined. Values of smoothed thermodynamic functions (heat capacity, entropy, enthalpy change and derived Gibbs energy) in the wide temperature range 9–1374 K were calculated.Graphical abstractSchottky anomaly of HoPO4.
