Preparation and Magnetic Properties of Cobalt, Tin, Nickel Modifi ed Barium Ferrite Magnetic Particles
碩士 === 國立臺灣大學 === 材料科學(工程)研究所 === 81 === @ 本實驗以鐵鋇之氯化鹽及添加金屬之金屬鹽類,氯化鈷、氯化鍚、 氯化鎳為原料,以碳酸鈉為沈澱劑,依分子式之比例,採化學共沈法、 生成共沈物再將共沈物加以熱處理,可形成鋇鐵鋇六方結晶,其分子式為鈷 鍚鎳型取代型鋇鐵氧,粒子大小約0.3∼0.4微米。@ 共沈澱程度受陽離 子濃度及共沈時間的影響、時間之增長及離子濃度增加皆有助於陽離子沈...
