Enthalpy and heat capacity of the intermetallic compound CsBi2 in the solid and liquid states

详细

Enthalpy of solid and liquid intermetallic compound CsBi₂ in the temperature range of 430–1225 K was measured by massive isothermal drop calorimeter. Approximation equations were obtained, and isobaric heat capacity and enthalpy change on melting were determined. The tables of recommended values of caloric properties in the range from 298.15 K to 1225 K were developed. The experimental uncertainty of enthalpy and heat capacity measurements were estimated to be within 0.35 and 1.0%, respectively. The obtained results were compared with the calculations according to the laws of ideal solutions.
