摘　　要：研究了纳米氧化铁颜料的制备工艺，采用超声振荡和固相法相结合的方法合成纳米氧化铁。采用正交设计研究方案试验了研磨时间、表面活性剂种类及用量、灼烧温度、灼烧时间等因素对粒径的影响。并运用极差法处理得最佳工艺条件：研磨30--60min，表面活性剂用量占反应物总量2％～3％，在500～600℃下灼烧2～4h。试验结果表明，在固相反应中引入超声振荡可大大减小粒子团聚问题，从而获得纳米级粒子。Through orthogonal experimental design, the preparation of iron oxide nanometer particles by ultrasonic-solid phase reaction was studied. The influence factors on the granule size were investigated. The optimum conditions were obtained by range method： attrition time 30-60 min, the dosage of surfactant 2 % -3 %, incandesce time 2-4 h under 500- 600 ℃. The results showed that ultrasonic could greatly reduce the granule coacervation in the solid phase reaction.
