Stability of Aluminium Titanate-Mullite Ceramic
钛酸铝-莫来石陶瓷热稳定性的研究

The stabilizing effect of mullite on aluminium titanate was studied in detail through XRD, RPD, SEM and EDS. The sintering temperature was found to thect 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.
