Abstract

Aluminum titanate solid solutions with empirical formulas of Al2Ti1‐xZrxO5, Al6(2‐x)(6+x)Si6x/(6+x)6x/(6+x)TiO5, and Al2(1‐x)MgxTi1+xO5 were synthesized by reaction sintering and annealed at 900° to 1300°C in air to evaluate the thermal stability. Substitution of Al in Al2TiO5 by Si and 2Al by Mg and Ti ions to form solid solutions such as AI6(2‐x)/(6+x)l‐Si6x/(6+x)□6x/(6+x)TiO5, and Al2(1‐x)MgxTi1+xO5 was effective in controlling the thermal decomposition, but substitution of Ti by Zr had little effect.
