CoFe2O4/BaTiO3-(Na0.5Bi0.5)TiO3 material and preparation method thereof
The invention discloses a CoFe2O4/BaTiO3-(Na0.5Bi0.5)TiO3 material and a preparation method thereof. The preparation method comprises the following steps: preparing 0.65BaTiO3-0.35(Na0.5Bi0.5)TiO3 powder with barium carbonate, titania, bismuth oxide and sodium carbonate as raw materials, carrying out granulation on CoFe2O4 powder and the 0.65BaTiO3-0.35(Na0.5Bi0.5)TiO3 powder, carrying out compression moulding in a die according to a 2-2 compounding layering staking arrangement mode, discharging rubber, and calcining. According to the CoFe2O4/BaTiO3-(Na0.5Bi0.5)TiO3 material and the preparation method thereof disclosed by the invention, as a ferroelectric phase and a ferromagnetic phase are co-fired together in a layering compounding mode according to the 2-2 compounding layering staking arrangement mode, mutual reaction between the ferroelectric phase and the ferromagnetic phase can be effectively inhibited so as to keep respective characteristics, and the CoFe2O4/BaTiO3-(Na0.5Bi0.5)TiO3 material is good in both ferroelectricity and ferromagnetism.
