According to the principles of simultaneous equilibria and mass equilibria, CuInSe2 (CIS) were prepared by total aqueous 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--H2O (T=298 K), and the equilibrium curves of lgc-pH were drawn.It was found Makeup Brush set 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 principles of simultaneous equilibria Cereal Bars and mass equilibria of the Cu+-In3+-Se2--NH3-L2--Cl--H2O 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.
