piezoelectric ceramics vibration sensor are obtained by applying a DC strong electric field to a ferroelectric ceramic for polarization treatment. It is a special piezo ceramic material that can convert electrical energy and mechanical energy into each other. When the piezo ceramic is subjected to m

The first is the separation of nucleation and growth process,which is promoting nucleation and controlling growth,to ensure that the nucleation rate is greater than the growth rate, that is, ensuring that the PZT materials piezo ceramic powder precursor is formed under a large degree of supercooling

The polarization of some dielectrics is very special. In a certain temperature range, their dielectric constants are not constant, but vary with field strength, and after removing the external electric field, these dielectrics are not neutral. There is residual polarization. In order to be analogous

The ultrasonic transducer is a sound pressure-electrical conversion device that can convert the surface acoustic energy and electrical energy.Since 1917, the French scientist Paul Langevin discovered the inverse piezoelectric effect, it is using quartz crystals as piezoelectric materials.The first p

What are the distance methods for ultrasonic distance transducer?In the ultrasonic distance transducer,distance methods generally have a single-shot dual-receiving type, and it is also a sonic logging method. In terms of composition, there are mainly three sound systems, sound insulators and electro

piezoelectric effect and dielectric effect of piezoelectric ceramic The piezoelectric effect is that when some dielectrics are deformed by an external force in a certain direction, polarization occurs inside, and positive and negative opposite charges appear on the two opposite surfaces thereof. Wh
