| Current-voltage characteristics of SnO2–Co3O4–Nb2O5–Cr2O3 ceramics prepared using planetary milling process are studied in dc, ac and pulse regimes. Although microstructure characterization rather confirms the visible homogeneity of sintered material, quite strong contribution of Joule heating to non-Ohmic behavior was revealed. The quality of the studied SnO2–Co3O4– Nb2O5–Cr2O3 ceramics for varistor application is not sufficient. This conclusion contradicts the view in previous publications by other authors. | |
