| dc.description | In this work, the effect of Sb2O5 content and sintering temperature on varistor properties of SnO2–Co3O4 based
ceramics was investigated. The ceramic materials were prepared by conventional mixing varying the amounts of
Sb2O5 in five levels (0.1, 0.2, 0.3, 0.4 and 0.5 mol %) and the sintering temperature in two levels (1350 and 1450
°C). Results show that sintering temperature significantly affects the breakdown voltage, being the effect more
prominent in the ceramic with 0.3 mol % Sb2O5. Moreover, an evident grain growth was produced but without
any apparent total densification. At 1450 oC, the optimum sintering temperature to achieve the lowest breakdown
voltages, Sb2O5 additions confer a beneficial effect but only up to 0.3 mol %. The nonlinearity coefficient is also
affected by sintering temperature but in an opposite manner because, at the same composition (0.3 mol %), while
the optimum nonlinearity coefficient is achieved at 1350 oC, the best breakdown voltage is obtained at 1450 oC. | |
