The enthalpy of the CsBi alloy in the temperature range of 432–1127 K of the solid and liquid states has been measured by the mixing method on a massive isoperibolic calorimeter. Approximation equations have been obtained, and the isobaric heat capacity and enthalpy changes on phase transitions have been determined. The estimated errors of the data on enthalpy and heat capacity of the melt are 0.75 and 1.5–2.0%, respectively. The enthalpy of the alloy formation in the liquid state has been determined. The obtained results have been compared with the calculations based on the laws of ideal solutions.
