                 7 Secrets About Piezo Crystals That Has Never Been Revealed For The Past 50 Years


Piezoelectric ceramicis a kind of functional ceramic material that can convert electric energy into mechanical energy or convert mechanical energy into electric energy. Although it is still a new type of piezo ceramic material in the family of ceramics,mini piezo ceramic discs has enjoyed rapid development and widespread use in recent decades due to its piezoelectricity,which not found in other ceramic materials and the resulting variety of electromechanical properties.The application of piezoelectric ceramics can still be roughly divided into piezoelectric vibrator and piezoelectric transducer categories. The former mainly uses the resonance characteristics of the vibrator itself, and requires stable performance such as piezoelectric, dielectric and elasticity, thickness mode vibration application,and high mechanical quality factor. The latter mainly converts one form of energy into another form of energy, requiring a high electromechanical coupling coefficient and a high quality factor.We also introduce the application of piezoelectric ceramics from this aspect. The application of high frequency transducer is in the piezoelectric vibrator.We use the application of piezoelectric ceramics as a transformer case. Piezoelectric ceramic transformers are solid state electronic transformers that work in audio or super audio. Compared with the traditional core wire wound electromagnetic transformer, the utility model has the advantages of small volume, light weight, not breakdown when in use, high temperature resistance of the transformer piezoelectric rings sensor itself, no fear of burning, no electromagnetic interference, simple structure, simple manufacturing process and mass production . Piezoelectric transformers are mainly used in driver + (, + (DC, DC) transformers, in addition, the piezoelectric transformer is also used in the military, that is, the use of its output electrode tip discharge detonating high-pressure detonator. Civil piezoelectric generator ceramic
applications are more such as neon drivers, high-pressure immobilizer, high-voltage electric shock stick, small light machine, radar, copiers, helium, neon and small carbon dioxide-based phosgene, etc. Piezoelectric ceramic transformer is formed by different components of the heteropolar.The crystal structure of the symmetric point group is achieved by using the inverse piezoelectric effect and the positive piezoelectric effect.
