Journal of Ceramic Science and Technology

The Journal of Ceramic Science and Technology publishes original scientific articles on all topics of ceramic science and technology from all ceramic branches. The focus is on the scientific exploration of  the relationships between processing, microstructure and properties of sintered ceramic materials as well as on new processing routes for innovative ceramic materials. The papers may have either theoretical or experimental background. A high quality of publications will be guaranteed by a thorough double blind peer review process.

The Journal is published by Göller Verlag GmbH on behalf of the Deutsche Keramische Gesellschaft (DKG). Edited by Yu-Ping Zeng, Shanghai Institute of Ceramics, Chinese Academy of Sciences, China.

Abstract

Li2O-stabilized β″-alumina powder was synthesized in the double zeta process with Al2O3, Na2CO3 and Li2CO3 as the starting materials. The effect of nano CuO additive as the sintering aid on phase formation, microstructure, mechanical and electrical properties of Li2O-stabilized β″-alumina ceramics was investigated by means of x-ray diffraction (XRD), scanning electron microscope (SEM), biaxial flexure test (BFT) and ionic conductivity test. The results indicated that the fracture strength of the samples improved with the addition of a low concentration of nano CuO, which can be attributed to the higher density and more uniform microstructure. The optimal amount of nano CuO was determined at about 1.5 mol%, with the addition of which the ionic conductivity was approximately twice as high as that of the sintered samples without any nano CuO.
