Formation and Decomposition of So!-Gei Synthesized Aluminum Titanate Nano Powders at the Presence of Fe2O3 Additive

摘要

Full formation of aluminum titanate compound at low temperatures was obtained by sol-gel method. With addition of various amount of Fe2O3 additive to tialite composition formation and decomposition of tialite phase have been investigated. X-ray diffraction (XRD), simultaneous thermal analysis (STA) and scanning electron microscopy (SEM) analysis showed that the formation of nano tialite at low temperatures (around 950°C) was improved at the presence of additive and decomposition rate of aluminum titanate to 01-AI2O3 and HO2 (Rutile) in sample with 5%wt Fe2C>3 was controlled with formation of Al2TiOs-Fe2TiOs solid solution,
