Lpp Diagrams – Stability diagrams

The new HSC Chemistry 7.0 can draw two types of phase stability diagrams. The new Tpp Diagram module calculates the diagrams on the basis of minimum Gibbs energy (area graphics) and the old Lpp Diagram module calculates the phase stability boundaries as lines based on the reaction equations (vector graphics). These two modules have their own option buttons in the HSC main menu, i.e. Tpp and Lpp Diagram buttons.

The Lpp Diagram module draws isothermal phase stability diagrams of three element systems, also known as predominance area diagrams or Kellogg-diagrams. For example, a Ti-Cl-O-diagram may show the stability areas of titanium-containing substances as a function of Cl2(g) pressures- and O2(g) pressures in the atmosphere.
