I-Piezoelectric ceramics iwuhlobo lolwazi olusebenzayo lwe-ceramic impahla engaguqula amandla emishini namandla kagesi komunye nomunye.Kungumphumela we-piezoelectric.Ngaphezu kwe-piezoelectricity, i-piezoelectric ceramics nayo ine-dielectricity, elasticity, njll., esetshenziswe kakhulu ekucabangeni kwezokwelapha, izinzwa ze-Acoustic, ama-acoustic transducers, ama-ultrasonic motors, njll.
Ama-ceramics e-piezoelectric asetshenziswa kakhulu ekwenzeni ama-ultrasonic transducers, ama-acoustic transducers angaphansi kwamanzi, ama-electroacoustic transducers, izihlungi ze-ceramic, iziguquli ze-ceramic, ama-ceramic discriminators, amajeneretha anamandla kagesi aphezulu, ama-infrared detectors, ama-surface acoustic wave, Amadivayisi we-electro-optic, amadivaysi okushisa nokuqhumisa, i-piezoelectric gyros, njll., ayisetshenziswa kuphela emikhakheni yobuchwepheshe obuphezulu, kodwa futhi ekuphileni kwansuku zonke ukukhonza abantu nokudala impilo engcono kubantu.
EMpini Yomhlaba Yesibili, kwatholakala izitsha zobumba ze-BaTiO3, futhi izinto zokwakha ze-piezoelectric kanye nokusetshenziswa kwazo kwenza inqubekelaphambili enkulu.FuthiI-nano BaTiO3 powderukwenza kube nokwenzeka ukukhiqiza i-BaTiO3 Ceramic enezakhiwo ezithuthuke kakhulu.
Ekupheleni kwekhulu lama-20, ososayensi bezinto ezibonakalayo abavela emhlabeni wonke baqala ukuhlola izinto ezintsha ze-ferroelectric.Ngokokuqala ngqa, umqondo wezinto ze-nano wethulwa ocwaningweni lwezinto zokwakha ze-piezoelectric, okwenza ucwaningo nokuthuthukiswa kwezinto zokwakha ze-piezoelectric, izinto ezisebenzayo, zibhekane nempumelelo enkulu, ebonakala ezintweni zokwakha.Ushintsho ekusebenzeni ukuthi izakhiwo zemishini, izakhiwo ze-piezoelectric, kanye nezakhiwo ze-dielectric ziye zathuthukiswa kakhulu.Lokhu ngokungangabazeki kuzoba nomthelela omuhle ekusebenzeni kwe-transducer.
Njengamanje, indlela eyinhloko yokwamukela umqondo wemitha ye-nano ezintweni ezisebenzayo ze-piezoelectric ukuthuthukisa izakhiwo ezithile zezinto zokwakha ze-piezoelectric (engeza ama-nanoparticles ahlukene ukuze enze ama-nano complexes ezintweni ze-piezoelectric) futhi (usebenzisa ama-piezoelectric nanopowder noma ama-Nanocrystals kanye nama-polymers enziwa ngezinto eziyinhlanganisela izindlela ezikhethekile) 2 izindlela.Isibonelo, emnyangweni wezinto ezibonakalayo we-Thanh Ho University, ukuze kuthuthukiswe i-saturation polarization kanye ne-polarization eyinsalela yezinto zobumba ze-ferroelectric, ama-Ag nanoparticles angeziwe ukuze kulungiswe "i-nano-multiphase ferroelectric ceramics esekelwe ku-nanoparticles yensimbi/i-ferroelectric ceramics";Okufana ne-nano alumina (AL2O3) /PZT,i-nano zirconium dioxide (ZrO2)/PZT kanye nezinye izitsha ze-nano ezihlanganisiwe ze-ferroelectric ukuze kuncishiswe impahla yokuqala ye-ferroelectric k31 futhi kukhuphule ukuqina kokuphuka;izinto zokwakha ze-nano piezoelectric nama-polymers ndawonye ukuze kutholwe impahla eyinhlanganisela ye-nano piezoelectric.Kulokhu sizofunda ukulungiswa kwe-piezoelectric ceramics ngokuhlanganisa izimpushana ze-nano piezoelectric nezithasiselo ze-nano eziphilayo, bese sifunda izinguquko zezakhiwo ze-piezoelectric kanye nezakhiwo ze-dielectric.
Silindele ukusetshenziswa okwengeziwe kwe-nanoparticles kuma-ceramics e-piezoelectric!
