| Abstract: | This paper uses both chemical coprecipitation and sol-gel to prepare BaTiO3-CoFe2O4 two-phase composite ceramic powders,and prepare BaTiO3-of CoFe2O4two-phase composite ceramic by molding and sintering at 1200℃.Test XRD and TEM,and study on their dielectric property,I-V and ferroelectricity.XRD shows that BTO ceramic is tetragonal structure and has good ferroelectricity,big dielectric constant and low dielectric losses.CFO ceramic is spinel structure.Composite ceramic is two-phase composite ceramic with ferroelectricity and magnetic property. |
