The ferroelectric Ba0.6Sr0.4TiO3 (BST) and dielectric MgO composites with three different structures: columnar, layered, and spherical inclusion were prepared by spark plasma sintering (SPS). The microstructure and dielectric properties were investigated. Results show that the columnar composite exhibits an appreciable tunability (44.3%) as high as that of pure BST while the permittivity has been reduced from 5872 to 3998 at 10 kHz at room temperature, leading to a reduction of permittivity without deterioration of tunability in the bulk ceramics. This is a feasible way to balance the permittivity and the tunability, which is very promising for tunable devices application.
