Low-Temperature Heat Capacity of Lanthanum Hafnate

详细

The isobaric heat capacity of the pyrochlore lanthanum hafnate phase was measured by adiabatic calorimetry in the temperature range 0–346 K. Thermodynamic functions (the entropy, entropy increment, and reduced Gibbs energy) were calculated to be used for modeling physical and chemical processes where lanthanum hafnate is involved and for optimizing lanthanum hafnate preparation processes.
