Homogeneous spindle-shaped γ-FeOOH crystallite were prepared by oxidizing the Fe(CO2)2(OH)2(1-x) suspensions system formed in the solution of FeSO4 and NaWCO3 by doping Y3+.
本文还对γ-FeOOH的脱水过程机制和以γ-FeOOH为中间体经热处理制备的纺锤形γ-Fe2O3磁性能作了初步探讨。
As spindle-shaped goethite particles are loose,coating them with SiO2, Ni(OH)2 and Co (OH)2 at different hydrothermal temperatures forms a transition layer of a-Fe2O3 ,which makes them compact effectively.
由于纺锤形铁黄粒子较松散的特点,通过在不同水热温度下包覆硅、钴或镍,使纺锤形铁黄脱掉大量凝并接触部分的羟基,形成一层α-Fe2O3过渡层,粒子得到了有效的密实化,从而制备了高性能的纺锤形金属磁粉。
