Barium titanate is a ceramic material with excellent piezoelectric properties, and its crystal structure is perovskite type. In barium titanate ceramics, barium ions and titanium ions occupy the vertex and face center positions of the cube, forming a special crystal structure. This structure endows barium titanate ceramics with excellent piezoelectric properties, that is, they can undergo deformation and generate voltage under the action of an external electric field, and vice versa.
The preparation methods of barium titanate piezoelectric ceramic chips mainly include sol-gel method, chemical coprecipitation method, solid phase method, etc. Among them, the sol-gel method is one of the most commonly used preparation methods. The method is to dissolve barium titanate in organic solvent, and then prepare piezoelectric ceramic chips through gel, drying, sintering and other steps. The chemical co precipitation rule is to mix barium titanate precursor solution with barium salt solution, generate barium titanate precipitate through precipitation reaction, and then prepare piezoelectric ceramic sheets through drying, sintering and other steps. The solid-state method involves mixing barium titanate powder with an appropriate amount of sintering aids, and then preparing piezoelectric ceramic sheets through steps such as pressing and sintering.
