Preparation of PbTiO3 Conductive Powders and Coatings
La<,2>O<,3> and Ce<,2>O<,3> were penetrated into PbTiO<,3> to obtain conductive powders, and then they were mixed with polyurethane and butyl acetate to prepare conductive coatings. The results showed that the electric property of modified PbTiO<,3> powders was improved by penetration of La<,2>O<,3> and Ce<,2> O<,3>. XRD patterns showed that some new compounds such as La<,2>Ti<,6>O<,15>, CeTi<,21>O<,38> and Pb <,0.634>La<,0.209>Ti<,0.948>O<,2.284> were formed, which led to the rapid increase of conductivity. The resistivity of modified PbTiO<,3> powders decreased to 3.88Ω·m. The coatings using modified PbTiO<,3> powders as fillings also had a good conductivity. When the PbTiO<,3> powders were 10％ and antisettle agent (bentonite) content was 0.50％, and mass ratio between polyurethane and butyl acetate was 1.05, the surface resistivity of the coatings fell down to 1.3× 10<8>Ω·m. This kind of conductive coatings could be used in electromagnetic shielding.
