由穩定化合物熔化焓提取二元系活度

Calculation the Activities from Binary Systems Containing Congruently Melting Compounds Using Their Melting Enthalpy

摘要: 本文從二元系中穩定化合物與液相平衡關系入手,導出了由穩定化合物的熔化焓計算二元系活度的新公式。通過對In-Sb二元系的活度計算驗證了本方法的可行性,并用這一新方法預報了半導體Ga-As二元系的活度。

Abstract: A new method of calculating activities from binary systems has been developed. The new formulae require that the phase diagrams must contain congruently melting compound and its melting enthalpy is known. Their feasibility is tested by applying the new formulae to In-Sb system. By this method, the activities of an important semi-conductor system Ga-As have also been predicted.
