With electrolytic manganese anode slime as raw material and high-purity manganese sulfate as the precursor, manganese tetroxide (Mn₃O₄) particles were prepared via a two-step oxidation method. The response surface methodology was adopted to optimize the processing parameters. On this basis, the effects of surfactants on the particle size, specific surface area and micromorphology of Mn₃O₄ were systematically investigated. The results show that under the optimal conditions including manganese and ammonia in a molar ratio of 1∶2, reaction temperature of 65 ℃ and reaction time of 40 min, the manganese content of the synthesized Mn₃O₄ reaches 71.1%. Surfactants exert negligible impacts on the phase composition and manganese content of Mn₃O₄, but obvious effects on its microscopic surface morphology, specific surface area and particle size. The Mn₃O₄ synthesized by adding polyvinylpyrrolidone presents a quasi-spherical morphology with uniform particles and narrow size distribution. With a particle size of 32.65 nm and a specific surface area of 18.49 m²/g, the synthesized product satisfies the quality standard of high-purity Mn₃O₄ in terms of manganese content.

以电解锰阳极泥为原料、高纯硫酸锰为前驱体，采用两步氧化法制备Mn₃O₄颗粒，通过响应面法优化工艺条件，在此基础上，研究表面活性剂对Mn₃O₄粒径、比表面积和微观形貌的影响。结果表明，锰氨物质的量比1∶2、反应温度65 ℃、反应时间40 min条件下，制备的Mn₃O₄锰含量为71.1%。表面活性剂对Mn₃O₄物相组成及锰含量影响甚微，但对Mn₃O₄颗粒表面微观形貌、比表面积和颗粒尺寸影响明显。添加聚乙烯吡咯烷酮制备的Mn₃O₄呈类球形，颗粒尺寸较均匀，且粒度分布范围窄，粒径为32.65 nm，比表面积为18.49 m²/g，锰含量符合高纯Mn₃O₄要求。
