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

A novel Na2WO4 ceramic with low sintering temperature was successfully synthesized by means of the reactive sintering process. The phase composition, microstructure and microwave dielectric properties of the Na2WO4 dielectric ceramic with different sintering temperature (600, 650, 680 and 700 °C) were investigated in detail using X-ray diffraction (XRD), scanning electron microscopy (SEM) and a vector network analyzer, respectively. Excellent microwave dielectric properties with a relative permittivity (εr) ∼ 3.45, a quality factor (Q×f) ∼ 38 244 GHz (at 13.64 GHz) and a temperature coefficient of resonant frequency (τf) ∼ -42 ppm/K was obtained at a sintering temperature of 680 °C for 2 h. The results indicate that the Na2WO4 ceramic is a promising candidate for low-temperature co-fired ceramic technology.
