Intermetallic Compounds of the Platinum Group Metals

temperatures of a number alloys niobium and tantalum with the platinum group metals are such as to warrant further attention. Of the many and varied coating methods developed for high temperature corrosion protection of nickel and cobalt-based alloys, pack aluminising remains one of the most economical and convenient processes.

The high thermodynamic stability of alloys composed of platinum group metals and group IVB and VB metals has been explained by an electronic interaction analogous to the Lewis acid-base concept for nontransition elements. The analogy is further demonstrated by the titration of palladium by addition of niobium. The activity of niobium in solid palladium was measured as a
