Heat capacity of sodium and potassium hexafluorophosphate

Abstract

Abstract The heat capacities of NaPF 6 and KPF 6 were measured in a broad temperature range using differential scanning calorimetry. The suitability of applying a modified Neumann Kopp rule to calculate the heat capacity of “PF 6 ” was evaluated in order to obtain a general method to predict the heat capacities of other hexafluorophosphates.
