Effects of W6+ substitution on the microwave dielectric properties of Ce2Zr3(MoO4)9 ceramics
Abstract
Low temperature sintered Ce2Zr3(Mo0.9W0.1O4)9 (marked as CZMW) ceramics were synthesized via the conventional solid-state reaction method. X-ray diffraction results showed that the CZMW ceramics belonged to a Trigonal system with R-3C space group, and without any impure phase formation. The experimental facts revealed that the density and grain morphology greatly affected the microwave dielectric properties. The samples sintered at 825∘C exhibited good microwave dielectric properties: εr=9.85, Q×f=22,980GHz (at 11.3GHz) and a satisfactory τf (−1.5ppm/∘C) value. It is suggested that the CZMW ceramics are suitable for low-temperature co-fired ceramic (LTCC) applications in microwave devices.
