Preparation and dielectric properties of ceramics in the SrBi2(Ta1−xNbx)2O9 solid solution system

Ceramics in the SrBi2(Ta1−xNbx)2O9 solid solution system were prepared by a solid state reaction process, and the dielectric characteristics were determined together with the microstructures. An increased dielectric constant and improved temperature coefficient of permittivity were achieved in this solid solution system, while the dielectric loss remained at the same level as that of SrBi2Ta2O9.
