摘　　要：研究了以黄钠铁矾渣为原料，采用滴加法制备透明铁黄的工艺条件，讨论了亚铁浓度、温度、通气量、搅拌速度及添加剂用量等因素对铁黄制备的影响。用XRD和TEM对产品进行表征。结果表明，铁黄粒子呈针状；长轴为95—125nm，短轴为18～25nm；无团聚现象，单分散性好。The technology of making transparent iron oxide yellow from iron vitriol residue of yellow sodium by dripping method has been studied. The factors such as the concentration of Fe（ Ⅱ ） ,temperature, air amount and rotation speed which affect the preparation of iron oxide yellow were discussed. The product has bee detected by methods of XRD and TEM, and the result shows that the shape of iron oxide yellow particle is needle-like and the major axis of particles is from 95 nm to 125 nm,the mean minor axis is from 18 nm to 25 nm. There are no conglomeration in the particles, which are well separated.
