摘　　要：以ＺｎＳＯ４·７Ｈ２Ｏ和ＦｅＣｌ３·６Ｈ２Ｏ为原料，在微量相转化催化剂存在下，利用沸腾回流的液相法制备了纳米铁酸锌微晶．当反应物总浓度高达１．２ｍｏｌ·Ｌ－１时，仍可获得粒径＜２０ｎｍ均匀粒子．研究了初始ｐＨ值对产物组成的影响．使用ＸＲＤ、ＴＥＭ、ＩＲ及磁强仪对产物进行了表征，并测定了所得产物的密度及比表面．Nano-ZnFe2O4 was prepared by a liquid catalytic phase transformation method at lower temperatures. In this new method ZnSO4&middot7H2O and FeCl3&middot6H2O were used as raw materials and trace FeSO4 as the catalyst. When the beginning concentration of the reaction system reached 1.2 mol.L-1, the densities and specific surface areas were determined respectively.
