Ternary system

A system with three independent components A, B and C.

It can be illustrated in a three-dimensional diagram The concentration ratio in percentage is indicated by the triangle coordinates on an equilateral triangle. The corner points of this concentration triangle completely correspond to the pure components A, B and C. The temperature axes are perpendicular to the triangle level thus creating three-dimensional condition planes.

Condition changes are illustrated on the ternary phase diagram (s. Phase diagram).
