【Abstract】 In this paper, we reported that synthetic technology orNTC ZnO-Cr2O3 ceramics and examination of its electrical conductivity. Experimental results show that relationship between electrical conductivity or electrical resistance and temperature follows Arrhenius linear rules, the specific heat-sensitive electrical resistances are between (3.1-9.5) x 103. This Vind of ceramics is a chemical stable, active response and moderate temperature heat-sensitive ceramics.更多还原
