Title: Thermodynamic Analysis on the Preparation of Mn-Zn Soft Magnetic Ferrite Precursor by Coprecipitation Method
Abstract: The thermodynamic analysis on the system of Fe(Ⅱ)-Mn(Ⅱ)-Zn(Ⅱ)-CO32--NH3-H2O is carried out. The relationship between pH value and the total concentrations of Fe(Ⅱ), Mn(Ⅱ) and Zn(Ⅱ) is obtained, and the field of coprecipitation of Fe(Ⅱ), Mn(Ⅱ) and Zn(Ⅱ) is obtained at a suitable pH value. The results show that the field of coprecipitation is included in the field of precipitation of Zn(Ⅱ), while the field of precipitation of Zn(Ⅱ) is determined by the reciprocal ship of [N]T and [C]T. Furthermore the field of precipitation of Fe(Ⅱ) is related with [C]T only. Confirming the coprecipitation of Fe(Ⅱ), Mn(Ⅱ) and Zn(Ⅱ) it has important significance to prepare Mn-Zn soft magnetic ferrite ultrafine.
