After quenching the above-mentioned
AZT ceramic from 1200 ¡ãC, X-ray
diffractograms indicated decomposition of the
aluminum titanate phase. The partial
decomposition of Al2TiO5 was supposed to
play an important role in improving the
thermal shock resistance of the alumina-based
ceramic on quenching. No significant Al2TiO5
decomposition was observed when the AZT
ceramic was quenched from 950 ¡ãC.1, 2 This
seems to be consistent with findings of Low
and Oo6 who report insignificant
decomposition of pure metastable aluminum
titanate because of low rates of atomic
diffusion below 1000 ¡ãC, but significant
decomposition in the temperature range
between 1000 ¡ãC and 1300 ¡ãC.
