Phase factor in the parametric design of primary crystallization surfaces of binary and ternary reciprocal systems

Previously derived thermodynamically substantiated and simple equations wer e used to gain insight into the effect caused by a dimensionless parameter DeltaZ(AX)/RT which characterizes melt reversible arrow solid AX equilibria (a phase factor), on melt reversible arrow solid and melt reversible arrow melt equilibria of quasi-binary joins of ternary reciprocal systems and on the melt reversible arrow solid diagrams of the entire ternary systems. Th e results hold for binary systems and for quasi-binary joins of any other t ype of system.
