目前喷雾热分解法制备超细复合粉末组分偏析控制研究中缺乏分析手段。详细介绍了一种用于研究组分偏析现象的溶剂萃取方法,即利用两种组分在同一溶剂中的不同溶解性来分析复合粉末的组分偏析形式的方法。该方法不仅简单,而且结果可靠。 The current spray pyrolysis method for the preparation of ultrafine composite powder segregation control component analysis of the lack of means. A solvent extraction method for studying segregation of components is described in detail, namely, a method for analyzing segregation of components of a composite powder by using different solubilities of the two components in the same solvent. This method is not only simple but also reliable.
