Abstract: The effect of the additives Bi2O3·3TiO2 and MgTiO3 on the properties of SrTiO3 based ceramics was studied, and scanning electron microscope(SEM) was used to observe the morphology of the products. The result indicated that dielectric constant could be increased and loss tangent could be decreased by additive Bi2O3·3TiO2, The material's temperature characteristic was improved by additive MgTiO3, and the its grain size was homogeneous.
Key words: SrTiO3, MgTiO3, Bi2O3·3TiO2, ceramics, high voltage capacitors
