Abstract

Using the 2 probe mothods, AC coductivities, dielectric loss factors, capacitances, and impedances were investigated to study. The electrical and sensing properties for SnO$_2$ added ZnO. In air The electrical conductivity of SnO$_2$added ZnO decrease by increasing the content of SnO$_2$, and the relative dielectric constants for 0.05, 5, 7 SnO$_2$ added ZnO are 55, 20, 14, respectively. In 3000ppm CO Gas. relative dielectric constants for 3, 5mol% SnO$_2$ added ZnO are 163, 68, respectively.
