Effect of Type of Solid Solution on the Thermal Stabilityof Aluminium Titanate

Abstract

Abstract: The effect of type of solid solution on the thermal stability of aluminium titanate (Al₂TiO₅) was investigated by using additives
to form different type of solid solution with Al₂TiO₅. It is shown that the formation of complete solid solution in both unstabilized
Al₂TiO₅ and Fe₂O₃-stabilized Al₂TiO₅ has the best effect on suppressing the thermal decomposition of Al₂TiO₅；interstitial solid solution and limited substitutional solid solution
are inferior to complete solid solution in stabilizing Al₂TiO₅；in contrast, the stability of Al₂TiO₅ which forms unequal-valency
substitutional solid solution is poorest.

Key words: aluminium titanate, thermal stability, thermal decomposition, solid solutio
