摘要: α-FeOOH出发制备γ-Fe2O3磁粉,要经过脱水、还原、氧化等步骤.现有的研究已经指出,α-FeOOH的结晶性质在γ-Fe2O3中得到继承.而且,磁粉的性质与粒子的结晶性质有很大关系.因此,对铁黄制备过程中影响因素的研究一直受到人们广泛的重视[1~3].

Abstract: Sodium oxyalate and sodium hexametaphosphate were used as dispersing agents in the preparation of geothite (α-FeOOH). The experimental results showed that the dispersers had the effect of shortening the reaction time, promoting the geothite particle uniformity, preventing the denlrites in the geothitae growth process, and controlling the length of geothite.
