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

Since the early 1980s, experimental studies of the standard enthalpies of f ormation of the binary intermetallic compounds of early transition metals w ith late transition metals and with noble metals have been a major long-ter m research project in this laboratory. Tabulated in this review are 290 ent halpy of formation values for 273 such compounds, all determined in this la boratory during the last two decades. The calorimetric methods used in thes e investigations have included solution calorimetry, solute-solvent drop ca lorimetry, and direct synthesis calorimetry. Among these methods, the direc t synthesis approach has been the most frequently used technique. In this r eview, our results will be compared with values published by other laborato ries and with values predicted by the Miedema semi-empirical model. However , the emphasis will be placed on the systematic variation from group to gro up in the periodic table. A few examples will be presented to show the corr elation between the enthalpy of formation and the pertinent atomic number i n the binary alloy Families. (C) 2001 Elsevier Science B.V.
