Novel titanium dioxide ceramics containing bismuth and antimony

We developed one kind of novel TiO2 ceramics with colossal dielectric constant by chemical modifications (Bi3+ and Sb5+). Colossal dielectric permittivity (CP) (104∼105) together with low dielectric loss (∼5.7%) can be obtained. In addition, all ceramics possess a good frequency (102∼106 Hz) and temperature (−150-200 °C) stability of dielectric properties.290
