Synthesis of Pure Hexagonal Copper Sulfide Micro-crystals with Symmetric Concaved Polyhedrons by Ethanol Solvothermal Method

Pure hexagonal copper sulfide micro-crystals with symmetric concaved polyhedrons were synthesized by ethanol solvothermal method and using CuSO₄ and S as raw materials, ethanol as solvent. The reaction was processed at 180 ℃ for 12 h. The composition, shape and size of synthetic copper sulfide micro-crystals are characterized by the equipments of XRD, FESEM, TEM and SAED. The result reveals that the copper sulfide crystals are symmetric concaved polyhedrons. It is a simple, gentle and effective synthesis method for micro-crystals materials.
