ABSTRACT

Al2TiO5 ceramics were sintered by a solid-state reaction. LAS (β-spodumene) and Fe2O3 were added to the Al2TiO5 composition for enhancement of sintering behavior such as mechanical strength and thermal shock resistance. The sintered body was much densified by addition of LAS and Fe2O3 because LAS formed the liquid-phase and Fe2O3 suppressed the grain growth. We have systematically investigated the sintering characteristics, microstructures, mechanical properties,and thermal shock resistance according to the change of the amount of additive. When the additive of LAS (20 wt%)-Fe2O3was added to Al2TiO5, it confirmed that superior mechanical properties of the fracture strength of over 120 MPa and the thermal shock resistance of over 1,200oC were achieved.
