In a ternary Phase Diagram can I calculate binary sections or isopleths between any two points of the diagram?
Consider the KCl-LiCl-RbCl ternary system. You can calculate each of the three binary (T vs composition) phase diagrams KCl-LiCl (simple eutectic system), KCl-RbCl (complete solid solution) and LiCl-RbCl (LiRbCl2 mixed salt) in the usual way as three separate binary calculations with KCl & LiCl, then KCl & RbCl, and finally LiCl & RbCl as components. Or you could specify three components, KCl, LiCl & RbCl and then calculate isopleths (fixed composition) corresponding to each binary system. For example, for the KCl-LiCl system you would define T as the Y-axis, KCl/(KCl-LiCl-RbCl) as the X-axis (0 to 1), and RbCl/(KCl-LiCl-RbCl) as constant (0 for the KCl-LiCl system, but within the ternary system it could have any value up to 1). To calculate a LiRbCl2-KCl section simply enter these two components, LiRbCl2 (or Li05Rb0.5Cl) and KCl, in the components window. The components need not be compounds, any valid chemical formula is permitted. For example, you could calculate the binary phase di
