Abstract

Abstract: Sb-doped CdSnO₃ solid solution powder was prepared by chemical coprecipitation in accordance with the formula CdSb_xSn_1-xO₃. XRD results indicated the 0<x<0.3. The electric resistance of the samples markedly decreased at first and then increased gradually with the doped Sb content. Samples with x=0.02 and 0.25 showed the lowest value of resistance. The mechanisms of solid solubility and conductivity of the system have been discussed.

Key words: CdSnO₃, solid solution, conductive mechanism, gas sensing material
