Factors affecting the functioning of solid state fluoride galvanic cells

First-principles calculations and thermodynamic modeling of the Re–Y system with extension to the Ni–Re–Y system

“…4(c) that the SSUB function was created based on the experimental data from [3], and that a discrepancy exists between the experimental and first-principles Gibbs energy. Several sources of error for measuring energies of solid state fluoride galvanic cells were given by Azad and Sreedharan [38]; factors which could have caused incorrect measurements of the energy of the cell involving the formation of Re 2 Y. The work by Rezukhina and Pokarev [3] suggests a room temperature enthalpy of formation around À45 kJ/mol-atom which is higher than all of the values of C14 Laves compounds reported in both experimental and computational studies done on HfeM 2 alloys by Levy et al [39] and on MeCr 2 alloys by Chen et al [40].…”
