Abstract

The specific heats of NdP₅O₁₄ and PrP₅O₁₄ were measured with a differential scanning calorimeter over the temperature range 385–440 °K. The ferroelastic phase transition was confirmed to be second order. The ferroelastic transition temperatures for NdP₅O₁₄ and PrP₅O₁₄ were 426.5 and 416.5 °K, respectively. A second thermal anomaly was observed in both materials approximately 20 °K below the ferroelastic transition.
