Abstract
As additive, economic and low resistivity material was useful in the fields of electrostatic prevention and electromagnetism screening. Antimony-doped tin oxide(Sb:SnO2)/talc composite was prepared for this purpose via a modified chemical deposition method using economic and natural talc as matrix. Effects of hydrolysis temperature, pH value, doping concentration of antimony, proportion of Sb:SnO2 to talc, calcination temperature and time on the resistivity of the composite powder were investigated. The construction of Sb:SnO2/talc conductive composite was characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The resistivity of Sb:SnO2/talc composite prepared at the optimum conditions decreased to 3.0×103 Ω•cm, at the same time its whiteness was greatly improved.
