Article Preview

The influence of TiO2 nano powder on the electrical properties and microstructure of TiO2 ceramics was studied. The results showed that nano additive reduces the size of TiO2 grain. The results also showed that the breakdown voltage and nonlinear constant of the samples were improved and the dielectric constant was reduced by doping nano-titania. An optimal composition dopant with 6 mol% nano-titania exhibited a low breakdown voltage of 11.3 V/mm, a nonlinear coefficient of 5.5, an ultrahigh relative dielectric constant of 7.11×104 and relatively low loss of 0.28.
