Piezoelectric ceramics imhando yeruzivo inoshanda ceramic zvinhu iyo inogona kushandura mechanical simba uye magetsi emagetsi kune mumwe nemumwe.Icho chinonzi piezoelectric effect.Pamusoro pepiezoelectricity, piezoelectric ceramics zvakare ine dielectricity, elasticity, nezvimwewo, izvo zvakashandiswa zvakanyanya mukufungidzira kwekurapa, Acoustic sensors, acoustic transducers, ultrasonic motors, nezvimwe.

Piezoelectric ceramics inonyanya kushandiswa mukugadzira ultrasonic transducers, pasi pemvura acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage jenareta, infrared detectors, pamusoro acoustic wave madivayiri, electro-optic Devices, kubatidza uye detonating zvishandiso, piezoelectric gyros, nezvimwewo, inoshandiswa kwete chete muminda yepamusoro-soro, asiwo muupenyu hwezuva nezuva kushumira vanhu uye kugadzira hupenyu huri nani hwevanhu.

MuHondo Yenyika II, BaTiO3 ceramics yakawanikwa, uye zvigadzirwa zvepiezoelectric nemashandisirwo azvo zvakafambira mberi.Uyenano BaTiO3 upfuita kuti zvikwanise kugadzira BaTiO3 Ceramic ine zvimwe zvemberi zvivakwa.

Pakupera kwezana remakore rechi20, masayendisiti ezvenyama kubva kumativi ose enyika akatanga kuongorora zvinhu zvitsva zveferroelectric.Kekutanga, pfungwa yezvishandiso zvenano yakaunzwa muzvidzidzo zvepiezoelectric zvinhu, izvo zvakaita kuti tsvakiridzo nekuvandudzwa kwezvinhu zvepiezoelectric, chinhu chinoshanda, chakatarisana nebudiriro huru, inoratidzwa mumidziyo.Shanduko yekushanda ndeyekuti iyo mechanical properties, piezoelectric properties, uye dielectric properties zvakavandudzwa zvakanyanya.Izvi pasina mubvunzo zvichave nemhedzisiro yakanaka pakuita kweiyo transducer.

Parizvino, nzira huru yekutora nano metre pfungwa mune inoshanda piezoelectric zvinhu ndeyekuvandudza zvimwe zvivakwa zvepiezoelectric zvinhu (kuwedzera akasiyana nanoparticles kugadzira nano complexes mune piezoelectric zvinhu) uye (uchishandisa piezoelectric nanopowders kana Nanocrystals uye mapolymers anogadzirwa kuita zvinhu zvinoumbwa ne special means) 2 nzira.Semuenzaniso, muDhipatimendi rezvinyorwa zveThanh Ho University, kuitira kuvandudza saturation polarization uye zvakasara polarization yeferroelectric ceramic zvinhu, Ag nanoparticles yakawedzerwa kugadzirira "nano-multiphase ferroelectric ceramics yakavakirwa pasimbi nanoparticles / ferroelectric ceramics";Zvakadai se nano alumina (AL2O3) /PZT,nano zirconium dioxide (ZrO2)/PZT uye mamwe nano composite ferroelectric ceramics kuderedza iyo yekutanga ferroelectric zvinhu k31 uye kuwedzera kuomarara kwekutsemuka;iyo nano piezoelectric zvinhu uye mapolymers pamwechete kuti vawane nano piezoelectric composite zvinhu.Panguva ino tichadzidza magadzirirwo epiezoelectric ceramics nekubatanidza nano piezoelectric poda ine nano organic additives, uyezve kudzidza shanduko yepiezoelectric properties uye dielectric properties.

Isu tiri kutarisira kuwedzera uye kuwedzera mashandisirwo e nanoparticles zvinhu mu piezoelectric ceramics!
