碩士 === 吳鳳技術學院 === 光機電暨材料研究所 === 95 === Mn-Zn ferrite and Ni-Cu-Zn ferrite prepared from the industrial waste by chemical coprecipitation method was studied in this research.(a)Mn-Zn ferrite was manufactured by using steel pickling liquid and used dry butteries as rawmaterials,reacting with excess hydrochloric acid,and coprecipitation with adding NaOH rate filtered solution.From the XRD patterns,the structure of Mn-Zn ferrite is only spinel cubic structure with the powder size of 10~40nm,measured from TEM by the VSM,the magnetic properties of Mn-Zn ferrite powder is Mr(residual magnetization)equal 0.694 emu/g,Ms(saturation magnetization)equal 58.8 emu/g,Hci(coercive force)equal 3.83 Oe.(b)Ni-Cu-Zn ferrite was prepared by using steel pickling liquid,nickel electroplating waste solution,copper electroplating waste solution and zinc electroplating soluction as raw materials,adjusting the corresponding iron concentrations by ICP-OES,and coprecipitation with adding NaOH rate the mixed soluting .The plase strute of Ni-Cu-Zn ferrite is only spinel cubic structure with the powder particle size of 5~20nm,the magnetic prepared of Ni-Cu-Zn ferrite is Ms saturation magnetization)equal 31.2 emu/g.According to some of the commercial products, this product can be prepared and must properties of this product measured by XRD,LCR,Q meter,SEM,TEM and VSM match with phone of corresponding commercial product.
