Abstract
Fourier Transform Infrared Spectroscopic (FTIR) investigation has been carried out to study the structural changes and coordination of Al and Ti in the sol-gel derived aluminium titanate system as a function of temperature (65°–1400°C). An analysis of the FTIR spectral patterns shows that both octahedral as well as tetrahedral coordinations are present up to 800°C. At 1100°C, octahedral coordination is more predominant due to the formation of α-alumina. At 1300°C and above, the coordination is purely octahedral due to the formation of aluminium titanate.
