STUDY ON STRUCTURAL STABILITY AND THERMOSTABILITY OF FeCl_3-GIC

The pure stage 1, stage 2, stage 3 and stage 4 FeCl 3 GICs were prepared by mixing method, and their structural stability and thermostability were investigated both in air and in some liquid media for some time by the technique of XRD and TG DTA. The results show that FeCl 3 GIC from pure stage 1 to pure stage 4 can be prepared using mixed method under suitable C/FeCl 3 molar ratio by adjusting the reaction temperature and the soaking time. These pure stage FeCl 3 GICs are quite stable in air, higher stability in water and acid liquid media but less stability in basic liquid media and some organic solvents and their degradation temperature is about 330 ℃.
