Using Thermal Analysis Studying Reaction Process of Forsterite with Iron Ore Tailings

摘要

In this paper, the iron ore tailings that the metallurgy castoff can be recycled were adopted to synthesize forsterite refractory materials, thermal analysis was used to analyze the reaction process of the forsterite. In the lower temperature, the water cirrhosis decomposed reaction in the reaction process of the forsterite was studied during 573～900K. In the higer temperature, the forsterite was formed during mainly 1400～1673K with the solid solution as the binder phase. In accordance with the heatflow change to confirm five characteristic temperature dots to fire the sample, then the SEM and ED AX were used to make sure the thermal analysis results, in this way, the firing technics can be offered.
