Characterization of BaTiO3 Nano-particles Prepared by Microwave Method
To explore a cheap and efficient method of synthesizing BaTiO3 nano-particles,BaTiO3 nano-particles were synthesized by the microwave method taking TiCl4 and BaCl2 as main mw materials.The BaTiO3 nano-particles were characterized by XRD,SEM,DRS,dielectric loss spectrum and TG-DTA.The results show that the synthesized BaTiO3 nano-particles were pure cubic crystal phase with uniform particle size of about 90 nm and good dispersion.The BaTiO3 nano-particles show excellent dielectric properties with band gap of 3.4 eV.A part of cubic phase BaTiO3 are transformed into tetragonal structure after calcining at 1 000 ℃,so the synthesized BaTiO3 nano-particles show a good thermal stability.
