【摘要】 采用二次化学共沉淀方法制备M型铁氧体BaFe₁₂O₁₉。采用X射线衍射（XRD）和傅立叶变换红外光谱（FT-IR）对制备产物进行物相组成分析,采用Peakfit软件对制备产物的低频区FT-IR谱进行分峰拟合。XRD分析结果表明:800～1200℃范围内制备的产物为BaFe₁₂O₁₉,未见其他晶态杂相。分峰拟合结果表明:800～400cm^-1范围内除BaFe₁₂O₁₉吸收峰,还存在Fe₂O₃和BaO吸收峰,说明中间产物BaO和Fe₂O₃未反应完全,以非晶态形式存在于BaFe₁₂O₁₉中;升高焙烧温度,BaO和Fe₂O₃会进一步反应生成BaFe₁₂O₁₉,温度升至1200℃时反应仍未进行完全;Peakfit软件适用于铁氧体FT-IR谱分峰拟合及辅助铁氧体化学组成分析。更多还原

【Abstract】 The M-type ferrite BaFe₁₂O₁₉ was prepared by the secondary chemical co-precipitation method.X-ray diffraction（XRD）and Fourier transform infrared spectroscopy（FT-IR）were used to analyze the phase composition of the prepared product, and Peakfit software was used to perform peak fitting of the low-frequency FT-IR spectrum of the prepared product.The XRD analysis results showed that the product prepared in the range of 800～1200℃ was BaFe₁₂O₁₉,and no other crystalline phases were found.The peak fitting results showed that in addition to the absorption peak of BaFe₁₂O₁₉,there were absorption peaks of Fe₂O₃ and BaO in the range of 800～400 cm^-1,indicating that the intermediate products BaO and Fe₂O₃ had not reacted completely, and existed in BaFe₁₂O₁₉ in amorphous form; When the calcination temperature was increased, BaO and Fe₂O₃ Would further react to form BaFe₁₂O₁₉,and the reaction was not yet complete at 1200°C;Peakfit software is suitable for ferrite FT-IR spectrum peak fitting and auxiliary ferrite chemical composition analysis.更多还原
