Abstract
Flake mica titania conductive pigment, which characteristically consists of both electrical conductivity and pearlescent effect when covered a layer of ATO (Antimony Doped Tin Dioxide) on its surface, has been prepared by using homogenous precipitation method with mica titania as substrate and urea as precipitant. The hydrolysis of urea and the conductive mechanism of the pigment were discussed and the different substrates of mica and mica titania were compared. Furthermore, this paper studied several critical technological parameters pertaining to the influences on electrical conductivity and pearlescent effect of the pigment such as molar ratio of Sn4+/Sb3+, coating quantity and the addition order, etc.
