Abstract

Continuous monazite solid solutions La(VO₄)_1–х(PO₄)_х were prepared by ceramic technology. Heat capacities of three samples (х = 0.25, 0.50, and 0.75) were measured by adiabatic calorimetry at low temperatures (5–350 K). Thermodynamic functions were calculated in the range of temperatures studied.
