Piezoelectric ceramics ndi mtundu wazidziwitso zogwirira ntchito za ceramic zomwe zimatha kusintha mphamvu zamakina ndi mphamvu yamagetsi wina ndi mnzake.Ndi mphamvu ya piezoelectric.Kuphatikiza pa piezoelectricity, zoumba za piezoelectric zimakhalanso ndi dielectricity, elasticity, etc., zomwe zakhala zikugwiritsidwa ntchito kwambiri pojambula zamankhwala, masensa acoustic, ma acoustic transducers, ma ultrasonic motors, ndi zina zambiri.

Piezoelectric ceramics amagwiritsidwa ntchito kwambiri popanga ma transducers akupanga, ma transducers apansi pamadzi, ma electroacoustic transducers, zosefera za ceramic, zosinthira za ceramic, ma ceramic discriminators, majenereta apamwamba kwambiri, zowunikira za infrared, zida zamagetsi zamagetsi, zida zamagetsi zamagetsi, zida zoyatsira ndi kuphulitsa, piezoelectric gyros, etc., amagwiritsidwa ntchito osati m'madera apamwamba kwambiri, komanso m'moyo watsiku ndi tsiku kutumikira anthu ndikupanga moyo wabwino kwa anthu.

Mu Nkhondo Yachiwiri Yapadziko Lonse, zida zadothi za BaTiO3 zidapezeka, ndipo zida za piezoelectric ndi ntchito zake zidapita patsogolo kwambiri.Ndiponano BaTiO3 ufazitheke kupanga BaTiO3 Ceramic yokhala ndi zida zapamwamba kwambiri.

Kumapeto kwa zaka za m'ma 1900, asayansi apadziko lonse lapansi adayamba kufufuza zida zatsopano za ferroelectric.Kwa nthawi yoyamba, lingaliro la zida za nano lidayambitsidwa mu kafukufuku wa zida za piezoelectric, zomwe zidapanga kafukufuku ndi chitukuko cha zida za piezoelectric, zida zogwirira ntchito, zimayang'anizana ndi kupambana kwakukulu, kuwonetseredwa muzinthu.Kusintha kwa magwiridwe antchito ndikuti zida zamakina, zida za piezoelectric, ndi dielectric zidasinthidwa kwambiri.Izi mosakayika zidzakhala ndi zotsatira zabwino pa ntchito ya transducer.

Pakalipano, njira yaikulu yogwiritsira ntchito nano mita lingaliro mu zipangizo piezoelectric ntchito ndi kukonza zina katundu piezoelectric zipangizo (kuwonjezera nanoparticles osiyana kupanga nano complexes mu piezoelectric zipangizo) ndi (pogwiritsa ntchito piezoelectric nanopowder kapena Nanocrystals ndi ma polima amapangidwa nsanganizo zipangizo ndi njira zapadera) 2 njira.Mwachitsanzo, mu dipatimenti zakuthupi ya Thanh Ho University, pofuna kukonza machulukitsidwe polarization ndi otsalira polarization wa ferroelectric ceramic zipangizo, Ag nanoparticles anawonjezera kukonzekera "nano-multiphase ferroelectric ziwiya zadothi zochokera zitsulo nanoparticles / ferroelectric ceramics";Monga nano alumina (AL2O3) /PZT,nano zirconium dioxide (ZrO2)/PZT ndi zida zina za nano ferroelectric ceramics kuti muchepetse zida zoyambira za ferroelectric k31 ndikuwonjezera kulimba kwa fracture;zida za nano piezoelectric ndi ma polima palimodzi kuti apeze nano piezoelectric composite material.Nthawi ino tiphunzira za kukonzekera kwa piezoelectric ceramics pophatikiza ufa wa nano piezoelectric ndi nano organic additives, ndiyeno kuphunzira kusintha kwa piezoelectric katundu ndi dielectric katundu.

Tikuyembekezera kuchulukirachulukira kwa zinthu za nanoparticles muzoumba za piezoelectric!
