【Abstract】 The resistivity of SnO2-based inert anodes was measured by two-probe method. The experimental results showed that the electrical conductivity of the anodes can be improved by adding in some oxides,such as Sb2O3, CuO and ZnO which may control the cation valency and improve the sinter performance. For the present anodes, the relationship of 1gρ-1/T is similar to that of a semiconductor.更多还原
