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, acicular r-Fe_2O_3 as the matrix, suspended in a strong alkaline solution containing different Co ~ (2 +) / Fe ~ (2+) molar ratio of the complex reaction, the final coercivity Hc> 700Oe Cobalt-based r-Fe_2O_3 magnetic powder.
