【摘要】 本文从二元系中稳定化合物与液相平衡关系入手,导出了由稳定化合物的熔化焓计算二元系活度的新公式。通过对In—Sb二元系的活度计算验证了本方法的可行性,并用这一新方法预报了半导体Ga—As二元系的活度。更多还原

【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.更多还原
