Product Description

Ultrasonic Piezo Ceramic Rings Disc Pzt8 Pzt4 Piezoelectric Ceramic Element For Welding Transducer Of Hot Selling

The reliability of piezoelectric ceramics is affected by the mechanical structure of the load, drive control, operating environment and other conditions. In most applications, users often want to use smaller piezoelectric ceramics for cost reasons. However, this makes piezoelectric ceramic components the weakest link in many mechanical design structures In addition, piezoelectric ceramic is a kind of relatively complex material, which is very sensitive. Improper operation can easily cause damage. The conversion efficiency is related to transducer material, vibration form, structure of mechanical vibration system (including support mechanism) and working frequency. Therefore, the problem of ultrasonic transmitter is solved. There are two kinds of materials for piezoelectric ceramic transducer: magnetostrictive metal and piezoelectric ceramic. Piezoelectric ceramic transducer is a kind of electronic ceramic material with piezoelectric characteristics. The main difference between piezoelectric ceramic transducer and typical piezoelectric quartz crystal without ferroelectric component is that the crystal phase of its main component is ferroelectric grain. Because ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vector of each ferroelectric grain is also lost.
