Influence of low concentration MgCo2(VO4)2 addition on microwave dielectric properties of Ba0.6Sr0.4TiO3 ceramics
چکیده انگلیسی

Ba0.6Sr0.4TiO3−x MgCo2(VO4)2 ceramics with x = 0, 0.5, 1.0, 2.0, and 5.0 wt% was fabricated via conventional solid-state reaction process. The effects of such additives on the structure, dielectric and tunability properties were systemically investigated. A small number of secondary phase identified as Ba3(VO4)2 appeared in Ba0.6Sr0.4TiO3−x MgCo2(VO4)2 ceramics when x is more than 5.0 wt%. With increasing of MgCo2(VO4)2 content, the peak values of permittivity gradually decreased and shifted to low temperature. The Ba0.60Sr0.40TiO3 added with 0.5 wt% MgCo2(VO4)2 possesses a dielectric constant of 2763, Q value of 267 at ∼1 GHz and tunability of 35.9% under dc electric field of 30 kV/cm at 10 kHz.
