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.   

Bu yazıda, geleneksel seramik üretim yöntemleri ile imal edilen% 8 mol Lanthana (Lantanyum oksit, La2O3) ile stabilize edilmiş Zirkonya (Zirkonyum Oksit, ZrO2) esaslı kompozitlerin üretim ve yoğunlaşma davranışları anlatılmaktadır. , La2O3 ile Stabilize edilmiş (dengelenmiş) zirkonyum dioksit (LSZ, mol% 8 La2O3 ile) termal darbeye karşı yüksek tolerans, düşük termal iletkenlik, mekanik özellikler, yüksek erime noktası, iyi bir faz dengesi ve mükemmel oksidasyon direnci gibi yüksek üstün sıcaklık özelliklerine sahiptir. Alüminyum titanat (Al2Ti05), erimiş metallerde iyi kimyasal dirençle birlikte, termal şok direnci ve düşük termal iletkenliğe sahiptir. Bu çalışmada, farklı yüzdelerdeki Al2TiO5 ile alüminyum titanat / LSZ seramikleri toz metalurjisi teknikleri kullanılarak hazırlandı. Mikroyapısal, mekanik ve termal özellikler XRD, SEM, dilatometre ve sertlik ile karakterize edildi. Hazırlanan seramiklerin suda soğutulmasıyla termal şok direnci davranışı da değerlendirildi. Sonuçlar, alüminyum titanatın LSZ matrisine eklenmesinin alüminyum titanat / LSZ seramiklerinin özelliklerini geliştirdiğini ortaya koydu.
