Formation and Decomposition of Sol-Gel Synthesized Aluminum Titanate Nano Powders at the Presence of Fe₂O₃ Additive

Abstract:

Full formation of aluminum titanate compound at low temperatures was obtained by solgel 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 950oC) was improved at the presence of additive and decomposition rate of aluminum titanate to α-Al2O3 and TiO2 (Rutile) in sample with 5%wt Fe2O3 was controlled with formation of Al2TiO5-Fe2TiO5 solid solution.
