摘要：

The thermal stability of two materials based on aluminium titanate, obtained through reaction sintering at 1450-degrees-C and heat treated in atmosphere of N2/H-2 90/10 was studied using spectroscopic techniques. The samples were analysed by reflectance in visible, UV and NIR, electronic paramagnetic resonance (EPR) and Mossbauer spectroscopy. These techniques give coinciding results with regard to the reduction of Ti4+ to Ti3+ and to changes in the structural site changing of Fe3+ in reducing atmosphere.
