Lead zirconate-based anti-ferroelectric ceramic material and preparation and application thereof
The invention relates to the technical field of electronic functional materials and devices, in particular to a lead zirconate-based anti-ferroelectric ceramic material and preparation and application thereof. The chemical general formula of the material provided by the invention is (Pb < 0.88 > Ba < 0.09 > La < 0.02 >) (Zr < 0.5-x > Sn < 0.4 > Ti < 0.1 + x >) O < 3 >, wherein the value range of x is more than or equal to 0.01 and less than 0.03. The lead zirconate-based anti-ferroelectric ceramic material with an ultra-low phase transition electric field and a high dielectric constant at room temperature is prepared through component regulation and control, has good energy storage and charge-discharge performance in a low electric field, is beneficial to development of large-capacitance capacitors, is expected to be applied to the fields of power semiconductor devices and the like, and has wide application prospects. And the application range of the anti-ferroelectric ceramic capacitor is expanded.
