Description

technical field [0001] The invention belongs to the field of ceramic materials, in particular to a piezoelectric ceramic material and a preparation method thereof. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. According to the use of ceramic materials, ceramic materials can be divided into ordinary ceramic materials and special ceramic materials. [0003] Ordinary ceramic materials are mainly made of feldspar, clay and quartz, which are typical silicate materials; while special ceramic materials are mainly made of high-purity artificially synthesized raw materials, which are formed and sintered by precise control technology, and generally have certain Special features to suit various needs. [0004] The main components of special ceramic materials are oxide ceramics, nitride ceramics, carbide ceramics, cermets, etc.; special ceramics have...
