摘要

New temperature stability Ba_(1−x)Sr_xV_2O_6 (0.35 ≤ x ≤ 0.55) microwave dielectric ceramics prepared by the conventional solid-state route were investigated. X-ray diffraction confirmed that all the specimens formed a solid solution single phase with orthorhombic structure. The microwave dielectric properties strongly depended on the compositions, densification and microstructure of the specimens. Furthermore, partial Sr ions substitution for Ba ions in Ba_(1−x)Sr_xV_2O_6 lattices not only successfully improved the temperature stability of BaV_2O_6-based ceramic but also promoted the sinterability of SrV_2O_6-based one. Out of these compositions, Ba_(0.5)Sr_(0.5)V_2O_6 sintered at 625 °C exhibited a near-zero τ_f together with a low permittivity ε_r ~ 11.5 and a quality factor Q × f ~ 14 100 GHz, which also showed good chemical compatibility with Al electrodes.
