Using the added electric furnace and the electric balance, I performed the phase equilibrium experiments by dry method in the Zn-Fe-Ga-S system at 900ﾟC and 800ﾟC, and obtained the phase equilibrium relations in the quaternary system at both temperatures. Reactants are synthetic ZnS, FeS, GaS and Ga_2S_3, and elements of Zn, Fe, Ga and S.Products are identified by a reflected microscope and an X-ray diffractometer. The identified phases are as following : sphalerite, wurtzite, alloy Y, Phase X, Phase Z, Phase U, Phase V, Phase W, pyrrhotite, alpha-iron, zinc-liquid, gallium-liquid, sulfur- liquid, GaS, Ga_2S_3The largest solid solution in the central portion of this quaternary system is (Zn, Fe, Ga)1-xS solid solution, and the second is Phase V solid solution. In the Zn-Ga-S system there exists cubic Phase U solid solution, and in the Ga-Fe-S system there exist cubic Phase Z solid solution, hexagonal Phase W solid solution and tetragonalPhase X.In the Zn-Fe-Ga system there exist zinc-liquid, gallium-liquid, alpha-iron, alloy Y and gamma-phase.

利用增设的电炉和电天平，在900 ℃和800 ℃下对Zn-Fe-Ga-S四元系进行了干法相平衡实验，得到了两个温度下四元系的相平衡关系。反应物为合成的ZnS、FeS、GaS和Ga_2S_3，以及Zn、Fe、Ga和S元素。产物用反射显微镜和X射线衍射仪鉴定。四元系中最大的固溶体是（Zn，Fe，Ga）1-xS固溶体，其次是V相固溶体。Zn-Ga-S系统中存在立方相U固溶体，Ga-Fe-S系统中存在立方相Z固溶体、六方相W固溶体和四方相X。Zn-Fe-Ga系统中存在锌液、镓液、α-铁、合金Y和γ相。
