摘要
Thermodynamic description of the Cs-In system has been developed by the CALPHAD modeling combined with first-principles calculations. From first-principles calculations, the enthalpies of formation of CsIn(3) and Cs(2)In(3) are predicted to be 14.76 and 16.79 kJ/mol atom, respectively. With these enthalpies of formation and phase equilibrium data, Gibbs energy functions of individual phases in the Cs-In system have been evaluated. The calculated phase diagram of the Cs-In system is compared with the experimental one showing good agreement with each other. (C) 2010 Elsevier Ltd. All rights reserved.
