What is FTIR as a Tool to Study High-Temperature Phase Formation in Sol–Gel Aluminium Titanate about?

A FTIR spectrum is used to study the formation characteristics of aluminium titanate precursor gel under the influence of temperature. From an analysis of the spectra of the gel heated at different temperatures in the 30-1400°°C range, it is found that both octahedral and tetrahedral Al-O coordinations are present up to 800°°C. At temperatures above 800°°C, the tetrahedral Al-O coordination decreases and becomes negligible at 1050°°C.alumina and rutile phases are formed at 1000°°C and the aluminium titanate phase is formed at 1300°°C. The Al-O coordination in aluminium titanate is found to be octahedral.
