Microwave Dielectric Properties of Low-Temperature Sinterable BaCe2(MoO4)(4) Ceramics
Low-temperature sinterable BaCe2(MoO4)(4) ceramics were prepared through solid-state ceramic route. X-ray diffraction, laser Raman spectroscopy and scanning electron microscopy techniques have been used to investigate the structure and microstructure of BaCe2(MoO4)(4) ceramics. The laser Raman study reveals distorted MoO(4)2- tetrahedral networks in the unit cell of the BaCe2(MoO4)(4) ceramics. The BaCe2(MoO4)(4) exhibits a dielectric constant of 12.3, an unloaded quality factor of 3320, and a temperature coefficient of resonant frequency of -37 ppm/degrees C.
