摘　　要：以钛白粉副产品绿矾为原料 ,采用胶溶相转移法制备超细氧化铁。实验表明 ,胶溶是制备工艺的关键步骤 ,其最佳条件为 :胶溶温度70～75℃、胶溶时间1～1.5h、溶液 pH值为8～9。所得产品96 45 %粒子粒径小于5μm ,在氯仿等有机溶剂中具有极好的分散性 ,有望在高档涂料。The by-product of titanium white pigment copperas was used to p roduce ultra-fine iron(Ⅲ)oxide by means of peptization-phase transference.The result shows that peptization is the key step in the processing.The best reaction conditions are as following:the peptization temperature is70～75℃;peptization time is1～1.5h;pH value is about8～9.The product has a good dispersivity in some organic solvents such as chloroform(CH 3 Cl).The96.4%of particle size is less than5μm.
