Preparation method of BiFeO3 porcelain added with Bi2O3-B2O3-SiO2 glass
The invention discloses a preparation method of BiFeO3 porcelain added with Bi2O3-B2O3-SiO2 glass. The method is characterized by comprising the following steps: step one, preparing BiFeO3; step two, preparing Bi2O3-B2O3-SiO2 glass; step three, adding the Bi2O3-B2O3-SiO2 glass obtained in the step two in mass percent of 5-9wt% in the BiFe3O obtained in the step to form a mixture, mixing the mixture with zirconia ball stone and deionized water, ball-milling and drying to obtain dried material, orderly pelleting and screening the dried material to form pelletized material; step four, manufacturing the pelletized material obtained in the step three into a sample, sintering to obtain a sintered sample; step five, grinding and cleaning the sintered sample obtained in the step four, uniformly coating the front and back sides of the ground and cleaned sintered sample with silver electrode slurry, sintering to obtain the BiFeO3 porcelain added with Bi2O3-B2O3-SiO2 glass. The low-loss porcelain dielectric material obtained by using the method disclosed by the invention is simple in preparation process and low in material cost, and has saturated ferroelectric hysteresis loop and low dielectric loss.
