  • A kind of conductive composite powder of TiO2 coated with Sb-doped SnO2(ATO) were prepared by wet chemical method.The morphology,resistivity,conductive mechanism of the ATO/TiO2 conductive composite powder was studied.ATO was absorbed to the surface of TiO2 particles by Van Der Waals force and electrostatic force,The complete network of conductive basic framework was determined by ATO content in TiO2 particles surface.Before reaching a percolation threshold(VC < 0.0689),the conductive ATO content was relatively smaller,the large-scale conductive network has not yet formed,so the resistivity of ATO/ TiO2 powder changed slow with ATO content.When VC=0.0689-0.1562,the probability of the chain network of conductive channel was greater,the connection between the ATO has undergone a qualitative change,and a three-dimensional conductive network structure was gradually formed,the resistivity of ATO/TiO2 conductive composite powder changed dramatically with ATO content,and when VC>0.1562,the conductive network connection became full,again the change of the resistivity of ATO/TiO2 composite powder becamed slow with ATO content.
