Where did the piezoelectric properties of piezoelectric ceramics come from?

Introduction to the polarization principle of Piezo Ceramic Plate Transducer

Polarization method

1) Oil-bath polarization method: The oil-bath polarization method uses methyl silicone oil as an insulating medium under certain polarization electric field, temperature and time conditions

　The method of polarizing the product

2) Air polarization method: The air polarization method is a method in which air is used as an insulating medium to polarize products under certain polarization conditions.

3) Air high-temperature polarization method: The air high-temperature polarization method uses air as an insulating medium, and the polarization temperature gradually decreases from above the Curie temperature (above TC10-20°C) to below 100°C, and the corresponding polarization electric field changes from higher Weak (about 30V/mm) gradually increase to stronger (about 300V/mm), the method of polarizing products, also known as high-temperature polarization method or thermal polarization method.　　

In general, this is indeed a very complicated process in the eyes of ordinary people, but it is more like basic common sense in the field of chemistry. Friends who study chemistry may understand the principle very well, and for Xiaobai, you Don’t be too nervous or anxious. You can refer to the text above to study the scientific principles in detail. If you have a certain chemical foundation, I believe you will understand it quickly. Of course, if there is a friend with a background in science, it may be a shortcut to learn from him with an humility.
