Electrical and microstructural properties of microwave sintered SnO2-based varistors Propriedades elétricas e microestruturais de varistores à base de SnO2 sinterizados por microondas

An investigation was made of the microstructural and electrical properties of SnO2-based varistors microwave sintered at 1200 ºC, applying a heating rate of 120 ºC/min and treatment times of 10, 20, 30, 40, 50 and 60 min. The system used in this study was (98.95-X) %SnO2.1.0%CoO.0.05%Cr2O3.X%Ta2O5,...
