| Abstract: | For the calculation and graphic construction of isothermal phase stability diagrams a procedure is proposed and described. In the calculations, coordinates of invariant points are determined first. Then phase boundaries connecting either two invariant points or an invariant point and a boundary point of a diagram are constructed. The algorithm described is limited to systems formed by three chemical elements, where besides the ideal gaseous mixture only single condensed phases are considered. Partial pressures of two gaseous species are used as coordinates of a diagram. |
