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

This work addresses the effects of TiO2 addition on the kinetics of in situ spinel formation and the properties of alumina-magnesia refractory castables. The kinetics of the formation of spinel in alumina-magnesia refractory castables with TiO2 addition (0 – 3 wt%) during firing at 1250 – 1450 °C for different times was investigated by means of XRD analysis. The reaction rate constant and apparent activation energy of spinel formation in castables calculated based on the Ginstling-Braunstein model varied with the firing temperature and TiO2 addition. A comparison of the castables' properties including permanent linear changes, apparent porosity and strength was discussed. The results demonstrated that the in situ reactions and properties of the alumina-magnesia refractory castables depend on the combined effects of TiO2.
