Niobium-deficient high-energy-storage silver niobate-based lead-free antiferroelectric ceramic and preparation method thereof
The invention discloses niobium-deficient high-energy-storage silver niobate-based lead-free antiferroelectric ceramic, the chemical formula of the ceramic is AgNbxTa0. 1O0. 5 + 2.5 x, x is molar percentage, and the value of x meets the electric neutrality. The invention also discloses a preparation method of the niobium-deficient high-energy-storage silver niobate-based lead-free anti-ferroelectric ceramic. According to the niobium-deficient high-energy-storage silver niobate-based lead-free antiferroelectric ceramic and the preparation method thereof provided by the invention, on the basis of doping 10% of Ta < 5 + > at the niobium site, the content of Nb < 5 + > is reduced, so that the prepared high-energy-storage silver niobate-based ceramic has the advantages of high energy storage density (6.1 J/cm < 3 >), high energy storage efficiency (62%), high breakdown electric field (317kV/cm) and high polarization intensity (54 [mu] C/cm < 2 >), the doping amount of doped ions can be reduced, and the service life of the ceramic is prolonged. Meanwhile, the energy storage performance of the anti-ferroelectric ceramic can be remarkably improved.
