The High-temperature Heat Capacity of LnPO4(Ln = La, Ce, Gd) by Drop Calorimetry
The high-temperature heat capacity of three lanthanide orthophosphates of monazite
structure have been measured in the temperature range (450 to 1570) K. The
data have been analysed in terms of a lattice term, represented by the 4f0 and 4f7
compounds LaPO4 and GdPO4, and an electronic term for CePO4. The calculated
excess heat capacity thus obtained is in reasonable agreement with that calculated
from the crystal field energies.
