Caloric properties of Cs60Bi40 alloy in the temperature range of 293-1125 K

Abstract

The results of the enthalpy measurements of the Cs60Bi40 alloy in the range of 431–1127 K of the solid and liquid states are presented. The experiments were carried out by the mixing method on a massive isoperibolic calorimeter. The estimated errors for enthalpy and heat capacity of the melt were 0.4 and 1.4%, respectively. It was shown that the heat capacity of the melt decreases linearly with increasing temperature, and its absolute value in the studied temperature range is 1.25–1.45 times higher than the additive value. Table of recommended values of caloric properties over the range from 298.15 K to 1175 K was developed.
