I-Piezoelectric ceramics luhlobo lolwazi olusebenzayo lwe-ceramics olunokuguqula amandla oomatshini kunye namandla ombane omnye komnye.Yimpembelelo ye-piezoelectric.Ukongeza kwi-piezoelectricity, ii-piezoelectric ceramics nazo zine-dielectricity, elasticity, njl., eziye zasetyenziswa ngokubanzi kwi-imaging yezokwelapha, i-Acoustic sensors, i-acoustic transducers, i-ultrasonic motors, njl.
Iiseramics zepiezoelectric zisetyenziswa ikakhulu ekwenzeni iitransducer ze-ultrasonic, ii-acoustic transducers zangaphantsi kwamanzi, ii-electroacoustic transducers, izihluzi ze-ceramic, ii-ceramic transformers, ii-ceramic discriminators, iijenereyitha zombane ophezulu, i-infrared detectors, izixhobo ze-acoustic wave, izixhobo ze-electro-optic, izixhobo ezivuthayo kunye neziqhushumbisi, I-piezoelectric gyros, njl., ayisetyenziswanga kuphela kwiinkalo zobugcisa obuphezulu, kodwa nakwimpilo yemihla ngemihla ukukhonza abantu kunye nokudala ubomi obungcono kubantu.
KwiMfazwe yeHlabathi yesiBini, iiseramikhi ze-BaTiO3 zafunyanwa, kunye nemathiriyeli ye-piezoelectric kunye nezicelo zazo zenza inkqubela phambili.Kwayenano BaTiO3 powderyenza ukuba kwenzeke ukuvelisa i-BaTiO3 Ceramic eneempawu eziphambili.
Ekupheleni kwenkulungwane yama-20, oosonzululwazi bezinto ezivela kwihlabathi liphela baqala ukuphonononga izinto ezintsha ze-ferroelectric.Ngethuba lokuqala, ingcamango yezinto ze-nano yaziswa kwisifundo sezinto ze-piezoelectric, ezenza uphando kunye nophuhliso lwezixhobo ze-piezoelectric, izinto ezisebenzayo, zijongene nokuphumelela okukhulu, kubonakaliswe kwizinto eziphathekayo.Utshintsho ekusebenzeni kukuba iipropathi zomatshini, iipropathi ze-piezoelectric, kunye neempawu ze-dielectric ziye zaphuculwa kakhulu.Oku ngokungathandabuzekiyo kuya kuba nefuthe elihle ekusebenzeni kwe-transducer.
Okwangoku, eyona ndlela iphambili yokwamkela ingqikelelo yemitha ye-nano kwizinto ezisebenzayo ze-piezoelectric kukuphucula iipropathi ezithile zezinto ze-piezoelectric (yongeza i-nanoparticles ezahlukeneyo ukwenza i-nano complexes kwizinto ze-piezoelectric) kunye (usebenzisa i-piezoelectric nanopowders okanye i-Nanocrystals kunye neepolymers zenziwe zibe yimathiriyeli edibeneyo. iindlela ezikhethekileyo) 2 iindlela.Ngokomzekelo, kwisebe lezinto eziphathekayo zeYunivesithi yaseThanh Ho, ukwenzela ukuba kuphuculwe i-saturation polarization kunye nentsalela ye-polarization yezinto ze-ceramic ze-ferroelectric, i-Ag nanoparticles yongezwa ukulungiselela "i-nano-multiphase ferroelectric ceramics esekelwe kwi-nanoparticles / i-ferroelectric ceramics";Njenge-nano alumina (AL2O3) /PZT,nano zirconium dioxide (ZrO2)/PZT kunye nezinye iiseramikhi ezidityanisiweyo ze-nano ze-ferroelectric ukunciphisa imathiriyeli yokuqala ye-ferroelectric k31 kunye nokunyusa ukomelela kokwaphuka;izixhobo ze-nano piezoelectric kunye neepolymers kunye ukufumana i-nano piezoelectric composite material.Ngeli xesha siza kufunda ukulungiswa kwee-piezoelectric ceramics ngokudibanisa i-nano piezoelectric powders kunye ne-nano organic additives, kwaye emva koko sifunde utshintsho kwiipropati ze-piezoelectric kunye neempawu ze-dielectric.
Silindele usetyenziso oluninzi nangakumbi lwe-nanoparticles kwi-ceramics ye-piezoelectric!
