Sodium bismuth titanate-based lead-free antiferroelectric ceramic material and preparation method thereof
The invention discloses a sodium bismuth titanate-based lead-free antiferroelectric ceramic material and a preparation method thereof, and belongs to the field of material preparation. Raw materials of the ceramic material are Bi2O3, Na2CO3, TiO2, SrCO3, MgO and SnO2, the Bi2O3, the Na2CO3, the TiO2, the SrCO3, the MgO and the SnO2 are mixed with zirconium ballstone and deionized water, ball milling, drying and sieving are carried out in sequence, then the mixture is pressed into a sample, heat preservation is carried out for 3 hours in air at a certain temperature, furnace cooling and grinding are carried out, and finally electrode slurry is coated, so that the sodium bismuth titanate-based lead-free anti-ferroelectric ceramic material is prepared. The sodium bismuth titanate-based lead-free antiferroelectric ceramic material prepared by the method disclosed by the invention has the advantages of obvious relaxation phenomenon, simple and environment-friendly preparation process, low preparation cost, large dielectric constant, small dielectric loss, excellent high-temperature stability, obvious frequency dispersion and wide application range, and has excellent application in a pulse power system.
