Abstract
Current–voltage characteristics, temperature dependences of the low-field dc conductivity and the relative dielectric permittivity of tin dioxide based SnO2–Co3O4–Nb2O5–Cr2O3 ceramics with CuO addition in the range 0–8 mol% are studied. These materials exhibit non-Ohmic conduction (the varistor effect). If 0.5 mol% CuO is added, the nonlinearity coefficient is increased from 54 to 75 and the electric field at fixed current density is decreased from 628 to 390 kV m−1. Higher amounts of CuO substantially diminish non-Ohmic behaviour. Thickness dependence of the nonlinearity coefficient and the electric field at fixed current density in SnO2 varistor ceramics is observed. Electrical properties are discussed in the frames of grain-boundary controlled conduction mechanism.
