The invention discloses a method for synthesizing silicon phosphide by using a mechanical ball milling method. The synthesis method is to prepare the mixture of lithium phosphide and silicon tetrachloride by mechanical ball milling under the protection of an inert atmosphere; after the reaction is completed, use an organic solvent to dissolve impurities and then filter to obtain a solid product, and drying Obtain silicon phosphide. The invention can mechanically ball-mill synthesize silicon phosphide at room temperature, and has the advantages of low energy consumption for ball-milling reaction, environmental friendliness, and easy industrialized large-scale production. |
