These materials usually have high strength, wear resistance, chemical inertness and specific electrical or thermal properties, and are suitable for use in capacitors, ceramic diaphragms, sensors, electrode materials and other fields, in which the performance and structure control of the material are crucial to its function. Ball milling, as a common preparation method, can effectively adjust the particle size, crystal structure and physical and chemical properties of the material through mechanical grinding and mixing. This makes ball milling one of the indispensable process steps in the production of ceramic dielectric materials.
