Silver niobate-based antiferroelectric ceramic material and preparation method and application thereof
The invention relates to a silver niobate-based antiferroelectric ceramic material and a preparation method and application thereof. The chemical formula of the silver niobate-based antiferroelectricceramic material is Ag1-xNaxNbO3, and x is greater than 0 and less than or equal to 0.5; the preparation method comprises the following steps: firstly, preparing Ag2O by utilizing AgNO3; then carryingout hydrothermal reaction by taking Ag2O, NaOH, Nb2O5 and NH4H2F as raw materials; preparing a granulation material from the hydrothermal reaction product, preparing a ceramic green body from the granulation material, carrying out plastic removal on the ceramic green body at a certain temperature, and sintering the ceramic green body at a certain temperature to obtain the silver niobate-based antiferroelectric ceramic material. According to the application, the silver niobate-based antiferroelectric ceramic capacitor is prepared by performing surface polishing on a silver niobate-based antiferroelectric ceramic material, printing silver paste and sintering silver under the temperature condition of 500-700 DEG C. The preparation method is simple, oxygen does not need to be introduced in the sintering process, and the effective energy storage density of the prepared product is high.
