Thermal Properties and Microstructural Characterization of Aluminium Titanate (Al2TiO5) / La2O3 -Stabilized Zirconia (ZrO2) Ceramics
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 1
Abstract
In this paper defined the productions and densification behaviour of 8 mole% Lanthana (Lanthanum oxide, La2O3) -stabilized Zirconia (Zirconium Oxide, ZrO2) based composites fabricated by the conventional ceramic production process. La2O3 stabilized zirconia (LSZ, with mole 8% La2O3) has excellent high temperature properties like low thermal conductivity, mechanical properties, elevated melting point, high toleration for thermal shock, superior oxidation resistance and well phase stability. Aluminium titanate (Al2TiO5) low thermal conductivity coupled with well chemical resistance in melted metals and exhibit extremely well thermal shock resistance. In this study, Aluminium titanate / LSZ ceramic with different proportions of Al2TiO5 was prepared by powder metallurgy techniques. The mechanical, thermal and microstructural properties were characterized by XRD, SEM, hardness and dilatometer. The thermal shock resistance performance under water quenching of the as-prepared ceramics was also estimated. As a results shown that the adding of aluminium titanate to LSZ matrix improves the properties of the aluminium titanate / LSZ ceramics.
