摘　　要：以250μm大小的锑粉为原料,在添加相同含量蒸馏水和烷基酚聚氧乙烯醚的条件下,采用湿法机械球磨的方式制备出不同类型的锑基粉末。采用XRD、TEM及FT-IR对制备的锑基粉末的结构、形貌及粒径大小进行了表征分析,研究了球磨时间和球磨转速对锑粉制备的影响。结果表明:当锑粉原料中加入1 ml/g蒸馏水和0.2 ml/g OP-10湿磨时,球磨转速为150 r/min、球磨时间为18 h可制备出分散良好、粒径分布均匀、平均粒径约为10 nm的锑粉。Nano-Sb powders were synthesized by wet ball milling with Sb powder of 250 μm as raw material and distilled water and alkylphenol ethoxylates emulsifier as additives. Crystalline phases, morphology and particle size of Sb powder samples were characterized by XRD, TEM and FT-IR for studying the effect of milling time and milling rates on the nano-Sb powders. Results show that when 1 ml/ g distilled water and 0.2 ml/g OP-10 are added into the raw material, and milling rates is 150 r/min and milling time is 18 h, the best dispersed nano-Sb powders are obtained, which has a narrow distribution of particle size with the average particle size of 10 nm.
