Stability of Aluminium Titanate-Mullite Ceramic

Abstract

Abstract: The stabilizing effect of mullite on aluminium titanate was studied in detail through XRD, RPD,
SEM and EDS. The sintering temperature was found to affect the stability of aluminium titanate. The content and the variety of mullite, as well
as annealing time, have influence on the composites. In addition, the mechanism of mullite suppressing the thermal decomposition of aluminium
titanate was discussed. Solid solution and mullite grain can suppress the grain of aluminium titanate, which results in the improvement on the
stability of aluminium titanate.

Key words: aluminium titanate, mullite, composite, thermal stability, thermal expansion coefficient
