이종현Jong Hyeon Lee, 원창환Chang Whan Won, 박경호Kyung Ho Park
Abstract
Li-ferrite powders were prepared by coprecipitation method. The crystal structure, the microstructure and the magnetic property of synthesised poveders were investigated using X-ray analysis, chemical analysis, SEM, and VSM. The synthesis of Li-ferrite by coprecipitation method was subjected to precipitate with stearic acid forming insoluble salt of Li^+ and then through calcination. The mole ratio of precursor(Li^-/Fe^(++))was a very important factor on the crystal structure and the magnetic property of product and the powders produced were weakly agglomerated. The optimum condition of synthesis were the mole ratio of FeSO₄: Li₂SO₄ : procipitan = 1 : 0.1 : 0.1, pH 95 and reaction temperature 80℃
