Abstract
Antimony doped tin oxide (ATO) Nano powder was prepared by co-precipitation method, selecting SnCl4 • 5H2O and SbCl3 as the main raw material, citric acid as dispersant, ammonia solution (1:3) as precipitant, which was characterized, analyzed and tested by XRD, SEM, and digital conductivity meter. The optimum technological condition is that evenly-scattered powder whose crystalline structure is rutile, particle is sphere, size is about 10nm and conductivity is 1.32 ×102 µs/cm can be obtained when the reaction temperature is 60°C, Sb doping ratio is 10%, pH value is 2, calcinations temperature are 600°C and calcinations time are 2 hours.
