Preparation method of niobium-doped barium titanate ceramic material capable of improving flexoelectric property
The invention discloses a preparation method of a niobium-doped barium titanate ceramic material for improving flexoelectric properties, and relates to the field of functional materials. The preparation method comprises the following steps: (1) carrying out ball-milling mixing on high-purity barium titanate powder and niobium oxide powder, and carrying out solid-phase sintering to prepare niobium-doped barium titanate powder; (2) preparing a to-be-used blank by using the powder; and (3) carrying out traditional sintering on the blank body to be used to obtain the niobium-doped barium titanate ceramic, and (4) the niobium-doped barium titanate ceramic is used for carrying out a flexoelectric property test, the flexoelectric coefficient of the niobium-doped barium titanate ceramic is 23-380 [mu] C/m, and the flexoelectric coefficient of the component with the optimal flexoelectric property is increased by 20 times compared with that of the pure barium titanate ceramic.
