Lead calcium zirconate stannate ceramic as well as preparation method and application thereof
The invention provides a lead calcium zirconate stannate ceramic and a preparation method and application thereof, and relates to the technical field of dielectric energy storage materials, the lead calcium zirconate stannate ceramic is synthesized and prepared through a traditional solid-phase reaction method and a two-stage sintering process, the chemical component of the ceramic is (Pb < 1-x > Cax) (Zr < 0.55 > Sn < 0.45 >) O < 3 > (PCZS), and x is 0.01, 0.02, 0.03 or 0.04. The PCZS ceramic powder with different Ca < 2 + > doping amounts synthesized by the invention is of a pure perovskite structure, the distribution and the size of sintered crystal grains of a sample are uniform and compact, the dielectric loss in a low-temperature section is lower than 3%, and the ceramic component has good frequency stability in a frequency band of 50kHz-1000kHz; the high energy storage density and energy storage efficiency of the material are of great significance in realizing large-scale integrated circuits.
