摘　　要：以黄钠铁矾渣为原料,用滴加法来制备透明铁黄时,首先要得到纯净的硫酸亚铁溶液,然后以氨水为沉淀剂制备晶种。本文介绍了晶种制备过程,考察了硫酸亚铁浓度、碱比、温度、通气量和搅拌速度等因素对晶种质量的影响。During the Preducing Process of Transparent Iron Oxide with Na2Fe（SO4）4（OH）12 by Dripping Method, Pure Green vitriosl solution must be got before making seed by Ammonia water which is used for Precipitating agent. The preducing process of seed is reporeted, and the factor such as density of green vitriol solution, proportion of Alkali, temperature, air amount and rotation speed which affect the qulity of seed were investigted.
