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。
