Influence of sintering conditions on Ni internal electrode and PTCR effect of the multilayer (Ba1.005−xYx)TiO3 ceramics Accession number: 20165103135240 Authors: Cheng, Xuxin 1 ; Li, Xiaoxia 1 ; Cui, Haining 1 Author affiliation : 1 College of Electronic Information and Electromechanical Engineering, Zhaoqing University, Zhaoqing Road, Duanzhou District, Zhaoqing; Guangdong; 526061, China Corresponding author: Cheng, Xuxin (cxx101@126.com) Source title: Journal of Materials Science: Materials in Electronics Abbreviated source title: J Mater Sci Mater Electron Volume: 28 Issue: 7 Issue date: April 1, 2017 Publication Year: 2017 Pages: 5200-5206 Language: English ISSN: 09574522 E-ISSN: 1573482X Document type: Journal article (JA) Publisher: Springer Science and Business Media, LLC Abstract: The influence of sintering conditions on the positive temperature coefficient of resistance (PTCR) characteristics and the Ni internal electrode in multilayer (Ba1.005−xYx)TiO3 (BYT) ceramics is investigated. The BYT ceramics were fired at 1160–1240 °C for 2 h in a reducing atmosphere and then reoxidised at 500–900 °C for 1–2 h. Results indicate that the room-temperature (RT) resistance for BYT ceramics—which were reoxidised at 750 °C for 2 h after sintering at different temperatures—decreased quickly when the sintering temperature was increased from 1160 to 1240 °C. As the firing temperature increased, the sample resistance jump [Lg(Rmax/Rmin)] increased initially and then decreased. In addition, the reoxidation temperature effect on the electrical properties and the PTCR effect on the specimens were also studied. Finally, the BYT ceramics showed a significant PTCR characteristic. They obtained a resistance jump greater than 3.06 orders of magnitude and a low RT resistance of 0.25 Ω at a 750 °C reoxidated temperature for 2 h after sintering at 1180 °C for 2 h in a reducing atmosphere. In addition, the sintering temperature influence on the Ni internal electrode surface microstructure is investigated using FSEM. © 2016, Springer Science+Business Media New York.
