BiY2F25O12/BaTiO3 lamellar ferroelectric composite material as well as preparation method thereof
The invention relates to a BiY2F25O12/BaTiO3 lamellar ferroelectric composite material as well as a preparation method thereof. The preparation method comprises the following steps: firstly preparing BiY2F25O12 powder by taking analytical pure Bi2O3, Y2O3 and Fe2O3 as raw materials; then granulating the BiY2F25O12 powder and the Bi2O3 powder; and then performing compression moulding on the two powder in a 2-2 composite barrier layer superposition and arrangement manner in a die and removing a PVA adhesive, calcining to obtain the lamellar ferroelectric composite material. According to the material provided by the invention, as a ferroelectric phase and a ferromagnetic phase are co-fired together by means of compositing in the 2-2 composite barrier layer superposition and arrangement manner for the BiY2F25O12 powder and the Bi2O3 powder, interaction of the two phases can be effectively inhibited so as to maintain the characteristics, so that the prepared composite material not only has relatively good ferroelectricity, but also has a relatively good ferromagnetic property.
