Classification of complete phase diagrams

In order to simplify the construction of phase diagrams the following limitations for the main types of binary complete phase diagrams are accepted  

The melting temperature of the pure nonvolatile component is higher than the critical temperature of the volatile component. 

There are no solid-phase transformations such as polymorphism, formation of solid solutions and compounds, and azeotropy in liquid-gas equilibria in the systems under consideration. 

Liquid immiscibility is terminated by the critical region (Li = L2) at high pressures and cannot be represented by more than two separated immiscibility regions of different types. 

All geometric elements of phase diagrams, their reactions and shapes (but not the combinations of these elements) can be illustrated by existing experimental examples.

To obtain die systematic classification of complete phase diagrams for binary systems the method of continuous topological transformation was used (Valyashko, 1990a,b 2002a,b). This method is based on the following two main principles ...
