Microstructures and dielectric properties of Ba0.5Sr0.5TiO3–Zn2TiO4 composite ceramics with low sintering temperature for tunable device applications
AbstractBa0.5Sr0.5TiO3–Zn2TiO4 composite ceramics with low dielectric constant and high tunability are fabricated at a relatively low sintering temperature of 1200°C via the conventional solid-state reaction route. Zn2TiO4 and Ba0.5Sr0.5TiO3 can be friendly coexistent in the composite material system. The dielectric constant is tailored from 2500 to 83 by manipulating the addition of Zn2TiO4 content from 0wt.% to 80wt.% weight ratio. The dielectric loss still keeps around 0.002 and the tunability is 10.3% under a DC-applied electric field of 30kV/cm at 10kHz for the 80wt.% Zn2TiO4 added Ba0.5Sr0.5TiO3 composite ceramics. These composite ceramics are promising candidates for multilayer low-temperature co-fired ceramics (LTCC) and potential tunable devices applications.
