摘要
本文以针状r-Fe_2O_3为基体,让其悬浮在含有不同Co^(2+)/Fe^(2+)摩尔比的强碱溶液中进行包复反应,最终得到矫顽力Hc>700Oe的包钴型r-Fe_2O_3磁粉。
In this paper,the r—Fe_2O_3 magnetic powder surrounded cobalt of coercive force Hc(700 Oe)is obtained by thesurrounding cobalt reaction of the r—Fe_2O_3 needle shape powder hanged in the strong basicity solution of the differentCo^(2+)/Fe^(2+) mole ratio.
