Study on microstructural influence of graphene on synthesis of BaTiO3

Abstract

A composite of polycrystalline Ferroelectric ceramics Barium titanate (BaTiO3) in perovskite (ABO(3)) structure with Graphene was prepared from BaCO3 and TiO2 mixture by sonicating, ball milled and followed by sintering at 1000 degrees C. Graphene of 0.04 mol added to BaTiO3 and sintered at 1000 degrees C to develop the crystalline and microstructural properties of composite. Composite sintered at 1000 degrees C temperature mostly shows pure barium titanate (BaTiO3) poly crystalline single phase material with presence of few secondary unwanted phases. X-ray diffraction (XRD) of the composite exhibits substantial effect of graphene on the crystal structure of barium titanate (BaTiO3). Micro Raman confirms the growth of BaTiO3.FESEM of Barium titanate (BaTiO3) with graphene (0.04 mol) almost shows change in crystal growth where grown of phases are clearly distinguished with porous free nature.
