This simulation shows a ternary phase diagram with a phase envelope. This diagram represents the phase behavior for mixtures of three components that are only partially miscible so that phase separations occurs. Click and drag the black dot, which represents the composition of the mixture. Each corner of the triangle is a pure component. The mass fractions for a phase or phases are displayed in a table(s). In the “diagram” view, check “tie lines” to view tie lines in the two-phase region. The endpoints of each tie line correspond to the compositions of the two phases in equilibrium (α and ß phases). Points along the orange phase boundary are in the α phase and points along the magenta boundary are in the ß phase.
