Preparation of barium titanate-strontium titanate accumulation ceramics using nanocubes and dielectric property

Abstract

Solvothermally synthesized strontium titanate (SrTiO3, ST) or barium titanate (BaTiO3, BT) nanocubes were accumulated and the dielectric properties were studied. Initially, the BT or ST nanocubes were pressed into pellets. BT and ST were deposited on the pellets by a solvothermal method. P-E hysteresis loops and S-E curves of BT- ST accumulation ceramics (BT on ST) showed ferroelectric responses. The dielectric constant of the accumulation ceramics was measured to be 70.6.
