摘　　要：阐明了化学法制备纳米粉的热力学条件，以及如何借助于材料的腐蚀状态图（Ｅ－ｐＨ图）确定沉淀成胶条件。试验结果表明，这种方法具有简单、直观、快捷等优点， 不但可以方便地确定单组分沉淀成胶条件， 而且对多组分共沉淀条件的确定更具有其优越性， 为化学法制粉提供了理论依据。This paper describes the thermodynamic condition of chemical method in making nano powder, and how to use corrosion figure (E pH figure) to determine the conditions of gel formation. The conditions of producing ZrO 2、Al 2O 3、ZrO 2 Y 2O 3、Al 2O 3 Y 2O 3 powder are confirmed. Some nano powders are made. The experimental results show that this method saves a lot of work to choose the conditions of gel formation. It provides a theretical base for chemical method of producing nano powder.
