超临界流体干燥法制备钡铁氧体超细粉末──Ⅱ.红外吸收光谱的研究
The Preparation of the Ultrafine Powder of BaFe12O19 by the Supercritical Fluid Drying (SCFD) Method──Ⅱ. The Study of the IR Spectra
【摘要】 对钡铁氧体的水凝胶、醇凝胶以及气凝胶的红外光谱进行了初步的观察,同时对不同焙烧温度及时间所得粉末的红外吸收光谱进行了考察。联系X-射线衍射结果,对钡铁氧体粉末的形成过程有了更进一步的认识。
【Abstract】 The IR spectra of hydrogel, alcogel and aerogel of BaFe12O19 were studied, and the ones of the powders calcined at different temperatures for different time were also studied. Relating with the XRD results,we further understood the formation process of BaFe12O19.
