The heat capacity pof ThO2 can be calculated as the phonon part of p for other actinide dioxides used as fuel in nuclear reactors. Precise determination of the phonon part of p of actinide dioxides is helpful to find out the contributions of other factores to p. In this paper we have, through studying the heat capacity of ThO2, developed a general method applicable to the study of p of other solids. In the developed method the three type-different experimental measurements made on a solid-heat capacity, thermal expansion and Debye-Waller factor-can be brought together for comparison. The application of this method to the study of p of ThO2 has enabled us to propose a better description of p of ThO2 than the generally accepted expression.
