Piezoelectric ceramic sheet refers to the general name of ferroelectric ceramics that are made of mixed oxides (zirconia, lead oxide, titanium oxide, etc.) by high-temperature sintering and solid state reaction, and have piezoelectric effect through DC high-voltage polarization treatment. It is a functional ceramic material that can convert mechanical energy and electrical energy.
Because of its good mechanical properties and stable piezoelectric properties, piezoelectric ceramics, as an important functional material sensitive to force, heat, electricity and light, have been widely used in sensors, ultrasonic transducers, micro displacement devices and other electronic components.
With the continuous research and improvement of material technology, as well as the rapid development of high-tech fields such as electronics, information, aerospace, etc., the production technology and application development of piezoelectric ceramics, as a new type of material with high intelligence, has become a hot topic of concern.
Piezoelectric ceramics Piezoelectric ceramics are a kind of electronic ceramic materials with piezoelectric properties. The main difference between piezoelectric ceramics and typical piezoelectric quartz crystals without ferroelectric components is that the crystal phases constituting their main components are all ferroelectric grains.
