TL;DRAbstract
The composite conductive powder with titanium dioxide powder covered by SnO2 and Sb2O3 was prepared by chemical coprecipitation technology. The orthographic tests showed that the optimal preparation condition is m(TiO2): m (SnCl4): m (SbCl3)=25:15:1, pH=1.5, hydrolysis temperature is 60℃ and calcinations temperature of the coprecipitation product is 700℃, the volumetric electrical resistivity of the powder is 77℃Ω•cm with size below 200 nm. Conductive coating was then prepared on aluminum alloy substrate with phenolic resin as binder. The volume resistivity of the conductive coating could be below 10^8 Ω•cm, meanwhile the surface of the conductive coating was smooth without defect.
