使用程序升温（２９８－８４３Ｋ）和等温（５２３Ｋ、５７３Ｋ和６２３Ｋ）热失重分析研究了多种方法制备的尖晶石结构铁酸盐ＭＦｅ２Ｏ４（Ｍ＝Ｆｅ、Ｍｎ、Ｃｏ、Ｎｉ）的还原行为，讨论了铁酸盐的制备方法、粒径和比表面积对其还原性能的影响。根据程序升温过程中和等温还原下铁酸盐的失重量分别定量地测定了其活化速度和失氧速度，得出了制备氧缺位铁酸盐ＭＦｅ２Ｏ４－δ（０＜δ≤１）的最佳温度和时间。
The reduction behavior of spinel ferrite MFe2O4 (M = Fe, Mn, Co, Ni) prepared by various methods was investigated by TG (298-843K) and isothermal analysis (523K, 573K and 623K) The preparation method of ferrite, the influence of particle size and specific surface area on its reduction performance were discussed. According to the weight loss of ferrite during the process of temperature increase and isothermal reduction, the activation rate and the rate of oxygen deprivation were quantitatively determined, and the best MFe2O4-δ (0 <δ≤1) Good temperature and time.
