采用同时平衡和质量守恒原理对全液相常温常压法制备CuInSe2( CIS)粉体过程中Cu+-In3+-Se2--NH3-L2--Cl--H2 O体系的热力学平衡进行分析，并绘制一系列的浓度对数lgc-pH值曲线.依据平衡图，发现溶液中[ NH3] T的变化主要影响溶液中[Cu+]T在体系中的浓度变化，[L2-]T的变化主要影响的是体系中[In3+]T的浓度变化，而[Cl-]T的变化对[Cu+]T和[ In3+] T的浓度变化均有影响，并可发现在pH 7.0~8.5时沉淀率最高.依据Cu+-In3+-Se2--NH3-L2--Cl--H2 O体系的同时平衡和质量守恒原理，采用全液相常温常压法，在pH 7.0~8.5条件下制备出粒径在20~50 nm且基本符合标准化学计量比的CIS纳米粉体.

According to the principles of simultaneous equilibria and mass equilibria, CuInSe2 ( CIS) were prepared by total aque-ous process at normal pressure and room temperature. A series of thermodynamic equilibrium equations were deduced for the complex system of Cu+-In3+-Se2 --NH3-L2--Cl--H2 O ( T=298 K) , and the equilibrium curves of lgc-pH were drawn. It was found from these equilibrium diagrams that [ NH3 ] T primarily affected the [ Cu+] T concentration,[ L2-] T influenced the [ In3+] T concentration, and [Cl-]T had impact on both. The highest precipitation coefficient was obtained at pH 7. 0-8. 5. As a result, based on the princi-ples of simultaneous equilibria and mass equilibria of the Cu+-In3+-Se2--NH3-L2--Cl--H2 O system ( T=298 K) and used total aqueous process at normal pressure and room temperature, CIS nanoparticles can be synthesized by adjusting the pH value to 7. 0-8. 5, and their size is about 20 to 50 nm.
