Improving the Strength of Al2TiO5 by Adding Spodumene

Abstract:

Article Preview

Aluminium titanate (Al2TiO5) is an excellent oxide ceramic material with a very low thermal expand coefficient. Aiming at improving the bending strength Al2TiO5, spodumene was used as additives for preparing Al2TiO5 and the effect of adding spodumene on the mechanical properties of Al2TiO5 was investigated in this paper. It was found that adding spodumene, instead of simple oxides, may significantly enhance the bending strength of Al2TiO5.
