Article Preview

In the present paper, magnesium dititanate (MgTi2O5, M2T) was introduced into aluminum titanate (Al2TiO5, AT) to form AT-M2T solid solution so that the thermal shock resistance of Al2TiO5 could be kept still good while without any decomposition. The effect of MgTi2O5 addition on thermal shock resistance of Al2TiO5 was investigated. The experimental results showed that the thermal shock resistance of Al2TiO5 began to decrease when a little amount of MgTi2O5 was added and then rose with the continuous addition of MgTi2O5, even overrunning that of pure Al2TiO5 when 30mol% MgTi2O5 was contained. It was found that fine solid solution was formed between Al2TiO5 and MgTi2O5, which enhanced the thermal shock resistance of Al2TiO5.
