Effect of calcination temperature of nanostructure Sb doped tin oxide (ATO) on electrical conductivity

摘要

Highly dispersed antimony doped tin oxide was prepared with SnCl4·5H2O and SbCl3 in anhydrous ethanol solution by co-precipitation method. XRD, FTIR and FESEM were employed to characterize structure and morphology of the product. Calcinations temperature plays an important role in ATO electrical conductivity. As a result, when the temperature is in the range of 500 - 700°C, the ATO exhibit a low volume resistivity, which can be attributed to the relative perfact crystallinity.
