Abstract： To explore the preparation conditions of one-dimensional conductive antimony doped tin oxide (ATO)， ATO nanorods were prepared with coprecipitated precursors using tin tetrachloride and antimony trichloride as Sn source and Sb source， NaOH as precipitator， Na₂SiO₃·9H₂O and NaCl as sintering aids. The effect of reaction conditions on the morphology of ATO nanorods during the precursor reaction was investigated. Conductive fibers was prepared at high temperature by depositing ATO precursor on the surface of aluminium silicate fibers， and the effect of calcination temperature on the electric conduction was investigated. The results show that roasting at high temperatures the as-prepared ATO turn into nanorods with regular morphology and good crystal shape with the help of Na₂SiO₃·9H₂O and NaCl. The resistivity of the conductive fibers achieves the lowest when the calcination temperature is 900 ℃.
