Preparation of Barium Titanate/Strontium Titanate Accumulation Ceramics with Necking Structure of Strontium Titanate Nanocubes

Abstract:

Barium titanate (BaTiO3) / Strontium titanate (SrTiO3) accumulation ceramics with necking structure of SrTiO3 nanocubes were prepared using a solvothermal method. XRD measurements confirmed SrTiO3 and BaTiO3 with a perovskite structure. The XRD peak intensities of the BaTiO3 increased significantly as the solvothermal reaction was repeated. After heat treatment of the SrTiO3 at 900°C, the particles grew larger and formed necked contacts with each other. As the solvothermal reaction was repeated in order to coat with BaTiO3, the density increased, the porosity decreased, and the thickness of the BaTiO3 layer increased.
