Microstructure, Properties and Kinetic Characterization in SnO2-Based Varistor with Addition of CuO Nano Particle, M.Sc. Thesis Sharif University of Technology ; Nemati, Ali (Supervisor) ; Seyyed Reyhani, Morteza (Supervisor)
Abstract
The aim of this study is to investigate the effect of Copper oxide on the microstructure, properties, and grain growth kinetic in Tin oxide- Based varistors. Copper oxide was mixed in Tin oxide with different concentration, including 0, 0.1, 0.25, 0.5, and 1 mol% and the samples were sintered at 1250, 1300, and 1350 oC. Then, phase and microstructural characterization was investigated and consequently, electrical properties were evaluated. According to results, Copper Oxide with forming the liquid phase through the sintering process, accelerated grain growth. It was found that, by increasing concentration of CuO, mean grain size was increased from 2.6 µm in 1250 oC and 5 hours to 17.1 µm...
