Solid-state galvanic cell measurements and oxide equilibration experiments are used to derive thermochemical quantities for a variety of acid-base stabilized alloys such as Nb-Pd, Nb-Rh, Ti-Pd, and Ti-Rh. The experiments have effectively resulted in the titration of palladium by niobium metal. The excess partial molar Gibbs energy of niobium at infinite dilution was determined to be -62 kcal/mole at 1000/sup 0/C and the Gibbs energy of formation of NbPd/sub 3.55/ is -42 kcal/mole. These results and those for the other systems are used to assess the importance of crystal field effects in the context of the generalized Lewis acid-base theory.
