Antimony doped tin oxide(ATO) was synthesized by co-precipitation method using Na2SnO3·5H2O,Sb2O3 as raw materials,HNO3 as precipitant.The obtained nano-powders have a particle size range in 7-10nm and a good crystallinity.The influence of reaction pH value,washing method,surfactant and temperature on product properties were studied by means of XRD,TEM,EDS,resistance tester for powder,zeta potential measurement.The results showed that reaction pH value had significant effect on the grain size and conductivi...
