Plasticity-enhanced lead lanthanum zirconate tin titanate-based antiferroelectric ceramic and preparation method thereof
The invention relates to plasticity-enhanced lead lanthanum zirconium tin titanate-based antiferroelectric ceramic and a preparation method thereof. The chemical formula of the zirconium tin lead titanate lanthanum-based anti-ferroelectric ceramic is (Pb < 0.975-x > La < 0.02 > Sr < x >) (Zr < 0.5 > Sn < 0.37 > Ti < 0.13 >) < 0.9975 > O < 3 >, x is smaller than or equal to 0.10; and sintering by adopting a flash sintering technology to prepare the plasticity-enhanced lead lanthanum zirconate tin titanate-based antiferroelectric ceramic. Wherein the initial electric field intensity is set to be 100-300 V/cm, and the temperature rise rate of the flash sintering furnace body is 5-15 DEG C/min; when the reading of the current detector reaches the order of magnitude of [mu] A, the electric field intensity is increased to 200-500V/cm; after the current density value reaches 10-30 mA/mm < 2 >, the stable current density is kept for 90-200 s; preferably, the temperature rise rate of the flash burning furnace body is 8-12 DEG C/min.
