Abstract Calculation of activities on the two-phase region boundaries in CaO-Al_2O_3-SiO_2 ternary system has been carried out. Relationships between the activities of components and the composition of intersection of tie-line and composition edges along two-phase boundaries have also been presented, upon which the activities may easily be read. This method can also be used in other ternary systems.
