Potential versus mole fraction diagrams

3 INTERMETALLIC PHASES AND COMPOUNDS 3.3.1 Potential versus mole fraction diagrams 

In the example above, the Ag Au system was seen to consist of two metals (either with complete miscibility or just a miscibihty gap) and to only form solid solutions. In many other systems the chemical similarity is much less pronounced. Solubility is limited and new 

The activity can also be obtained from voltage measurements versus the pure phase A as the reference electrode. But in the case of the formation of intermetallic phases or 

The more complex diagrams have led to the development of some modifications of the methods to determine the characteristic thermodynamic functions. This will be described in the following chapters.
