| description | The synthesis method comprises the following steps that S1, a silver nitrate solution is prepared through silver nitrate and a solvent, and the solvent is selected from one or more of ethylene glycol, glycerol, N, N-dimethylformamide, n-caprylic alcohol and n-heptanol; s2, adding a dispersing agent and a wafer regulating agent into the silver nitrate solution; s3, carrying out reduction reaction in a closed reaction kettle; and S4, the reaction liquid is subjected to aftertreatment, and the silver powder is obtained. According to the method, a one-step solvothermal method is adopted, operation is easy, a solvent serves as a reducing agent at the same time, no reducing agent needs to be additionally added, the introduction amount of exogenous impurities is reduced, the product is high in purity and regular in morphology, the product is submicron flaky silver powder, and the particle size is 200-600 nm; the silver source utilization rate is high, and the yield can reach 95% or above.
