Abstract: Based on the principle of thermodynamics a formula for calculating activities by intermediate compounds enthalpy of fusion has been derived from binary phase diagram. The feasibility of calculation method has been tested for In Sb system using the activities obtained from experiments and used in many literatures, and the results of calculation are in good harmony with that of experiment. The activities of Ga As, Ga Sb and In As semiconductor binary systems have been calculated using the new formula.
