摘要:
用湿化学法在TiO2颗粒表面包覆ATO制得ATO/ TiO2复合导电粉;运用TG－DSC、XRD、XPS、SEM、和电导率测试等手段对ATO/TiO2导电粉进行了表征.结果表明：煅烧温度对SnO2的晶化程度、Sb的价态、ATO/TiO2导电粉的导电性产生影响.电导率－温度（lnσ－T）关系呈抛物线（100～900 ℃）:上坡段（150～400 ℃），温度增加，无定形SnO2逐渐晶化，电导率增加，导电性上升，溶入SnO2的Sb3+ Sb5+转变，载流子浓度加大，包膜层多孔结构逐渐致密化；底部平台（400～600 ℃），SnO2晶化结束, Sb3+ Sb5+转变趋于完成，电子散射趋于最低，电导率最大，导电性达到最佳;下坡段（600～900 ℃），Sb3+ Sb5+转变发生逆转，TiO2基体颗粒长大，锐态型向金红石型转变，破坏包膜结构，电导率上升，导电性恶化.
Abstract:
ATO/TiO2 coated by Sbdoped SnO2, and conductive composite powders were prepared by wet chemical method. ATO/TiO2 conductive composite powders were characterized by differential thermal differential scanning calorimetry (TGDSC), Xray diffraction (XRD), Xray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and conductivity test. The research results were the influence of the calcination temperature on the SnO2 crystallization degree, the Sb valence, the conductivity of the ATO/TiO2 conductive powder were found. Resistivity  temperature (ρT) relations was the Ucurve (100—900 ℃). During the uphill (150—400 ℃), temperature increased, amorphous SnO2 crystallized gradually, and the conductivity increased, Sb3+ Sb5+, carrier concentration increased, the porous structure of coating layer gradually densed; during the platform at the bottom (400—600 ℃), the crystallization of SnO2 ended up, Sb3+ Sb5+ change tended to completion, electron scattering tends to a minimum, the resistivity was the lowest, the conductivity was optical. During the downhill sections (600—900 ℃), Sb3+ Sb5+ change reversed, TiO2 matrix particles grow up sharply, the acutetype tended to rutiletype changes,  the coated structure was damaged, the resistivity increased, the conductivity  deteriorated.
