The standard enthalpies of formation of the compounds of early transition metals with late transition metals and with noble metals as determined by Kleppa and co-workers at the University of Chicago — A review

Abstract

Since the early 1980s, experimental studies of the standard enthalpies of formation of the binary intermetallic compounds of early transition metals with late transition metals and with noble metals have been a major long-term research project in this laboratory. Tabulated in this review are 290 enthalpy of formation values for 273 such compounds, all determined in this laboratory during the last two decades. The calorimetric methods used in these investigations have included solution calorimetry, solute–solvent drop calorimetry, and direct synthesis calorimetry. Among these methods, the direct synthesis approach has been the most frequently used technique. In this review, our results will be compared with values published by other laboratories and with values predicted by the Miedema semi-empirical model. However, the emphasis will be placed on the systematic variation from group to group in the periodic table. A few examples will be presented to show the correlation between the enthalpy of formation and the pertinent atomic number in the binary alloy families.
