摘要 通过红外光谱、差热分析、透射电镜等测试手段观察了非晶态d-FeOOH热处理的相转化温度及相转化过程. 实验结果表明,在空气气氛中,非晶态d-FeOOH对热敏感,直接相转化为纳米级a-Fe2O3, 且其热处理过程只伴随微量的g-FeOOH生成. Phase transformation temperature and process of thermal treatment to amorphous -FeOOH particles were clarified by differential thermal analysis (DTA), infrared spectroscopy (IR) and transmission electron microscopy (TEM). According to preliminary experiments in air, amorphous d-FeOOH is sensitive to heat and directly transformed into a-Fe2O3 nanoparticles. Further more, during the course of the thermal treatment, tiny FeOOH is produced .
