Abstract
AbstractThe synthesis of pure phase Cu3SnS4 is of great significance for improving its material properties. Here, the control law of Cu and Sn element ratio on the synthesis of pure phase Cu3SnS4 from physical and chemical methods was analyzed through literature research. The results: (1) the adjustment of the Cu‐to‐Sn ratio metal elements as a phase control parameter has the characteristics of flexibility and controllability. (2) When the precursor component is rich in Cu and the chemical potential of the medium and high sulphur is high, the phase will develop to a wider thermodynamically stable region of Cu3SnS4. By adjusting the Cu‐to‐Sn ratio elements, when the release rate of anions and the reaction rate of cations adapt to each other, the thermodynamic reaction conditions can be well satisfied, which is beneficial to the preparation of pure phase Cu3SnS4. (3) The phase control method of Cu and Sn element ratio of template seed crystal can not only realize the reasonable regulation of Cu and Sn element ratio but also control the synthesis of phase more accurately. The results of this paper have certain reference values for the application of new materials synthesized by adjusting the proportion of elements.
