Phase diagrams of the 11th group metals

1 Phase diagrams of the 11th group metals. The intermetallic reactivity patterns of Cu, Ag and Au are similar, with no compound formation in the middle of the Periodic Table (groups 5-9 for Cu and Ag, about 6-9 for Au). 

The general reactivity pattern of the 11th group metals shown in Fig. 5.31 may be compared with that of the previous metals (of the 8th, 9th and 10th groups) summarized in Fig. 5.25. All these metals form compounds with the lanthanides and several
