摘　　要：以钛白粉厂副产物硫酸亚铁为原料,以氨水为沉淀剂,采用空气氧化法制备超细透明氧化铁黄.分别研究了影响晶种形成和晶体生长的主要影响因素.通过优化实验,得出了最佳工艺条件.晶种制备阶段:温度为30℃,空气流量为2L/min,溶液的pH为4～6,搅拌速度为400r/min,Fe2+浓度为1mol/L.晶体生长阶段:温度为85℃,空气流量为2L/min,溶液pH为4～6.A process of preparing superfine transparent iron oxide with the by-products of ferrous sulfate was described.The process included two steps：the yielding and growing of crystals.Several key factors affecting the two steps were studied respectively such as effects of Fe2＋ concentration,air flow rate and stirring rate and reaction temperature and pH values.
