Preparation of Barium Titanate-Coated Strontium Titanate Accumulation Ceramics by Solvothermal Synthesis and their 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 was deposited on the pellets by a solvothermal method. P-E hysteresis loops and S-E curves of BT-coated ST accumulation ceramics (BT on ST) showed ferroelectric responses. The dielectric constant of the accumulation ceramics was measured to be 70.6.
