Abstract

In the present work, BaLaAlO4 ceramics with orthorhombic structure similar to K2SO4 in space group P212121 were prepared by a solid state sintering process. The dense BaLaAlO4 ceramics with minor amount of secondary phase have a low dielectric loss and a temperature stable dielectric constant with obvious frequency dependence. A dielectric constant around 15 was obtained at 12 GHz in the present ceramics together with a Qf value over 5,000 GHz.
