PiezoelectricCeramics (PZT) materials are categorized as functional ceramics. In sensors they make it possible toconvert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.PiezoelectricCeramics materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.
Piezoelectric ceramics have sensitive characteristics and can convert extremely weak mechanical vibrations into electrical signals, which can be used in sonar systems, weather detection, telemetry, environmental protection, household appliances, etc. Earthquakes are devastating disasters, and the source of the earthquake is deep in the earth's crust. It was difficult to predict before, leaving human beings in an embarrassing situation where they can do nothing. Piezoelectric ceramics are sensitive to external forces so that it can even sense the disturbance of the air caused by flying insects flapping their wings more than ten meters away. Using it to make piezoelectric seismographs can accurately measure the intensity of an earthquake and indicate the location and distance of the earthquake. This cannot but be said to be a great skill of piezoelectric ceramics.
In terms of energy conversion, using piezoelectric ceramics to convert external force into electrical energy, piezoelectric igniters, mobile X-ray power supplies, and shell detonators can be manufactured. There are flints made of piezoelectric ceramics in electronic lighters, and the number of ignitions can exceed 1 million. Using piezoelectric ceramics to convert electrical energy into ultrasonic vibration, it can be used to find the position and shape of underwater fish, non-destructive testing of metals, ultrasonic cleaning, ultrasonic medical treatment, and various ultrasonic cutters, welding devices and Soldering iron, processing plastic and even metal.
Commonly used piezoelectric ceramics include barium titanate, lead zirconate titanate binary system, and the third type ABO3 added to the binary system (A represents divalent metal ion, B represents tetravalent metal ion or the sum of several ions is positive four Valence) type compounds, such as: Pb (Mn1/3Nb2/3) O3 and Pb (Co1/3Nb2/3) O3 and other components composed of the ternary system. If a fourth or more compounds are added to the ternary system, a quaternary or multi-component piezoelectric ceramic can be formed. In addition, there is a kind of metaniobate piezoelectric ceramics, such as potassium sodium metaniobate (Na0.5•K0.5•NbO3) and barium strontium metaniobate (Bax•Sr1-x•Nb2O5), etc. They are not Toxic lead is good for environmental protection.

The piezoelectric ceramics are sensitive to external forces so that they can even sense the air disturbance caused by flying insects'flapping wings more than a dozen meters away and convert extremely weak mechanical vibrations into electrical signals. This characteristic of piezoelectric ceramics can be used in sonar system, weather detection, telemetry environmental protection, household appliances and so on.
