Abstract
The thermal stability of two materials based on aluminium titanate, ob tained through reaction sintering at 1450-degrees-C and heat treated i n atmosphere of N2/H-2 90/10 was studied using spectroscopic technique s. The samples were analysed by reflectance in visible, UV and NIR, el ectronic paramagnetic resonance (EPR) and Mossbauer spectroscopy. Thes e techniques give coinciding results with regard to the reduction of T i4+ to Ti3+ and to changes in the structural site changing of Fe3+ in reducing atmosphere.
