Lisebelisoa tsa piezoelectric ke mofuta oa tlhaiso-leseling e sebetsang ea ceramic e ka fetolelang matla a motlakase le matla a motlakase. Ke phello ea piezoelectric. Ntle le piezoelectricity, li-piezoelectric ceramics le tsona li na le dielectricity, elasticity, jj, tse 'nileng tsa sebelisoa haholo litšoantšong tsa bongaka, li-sensors tsa Acoustic, transducers ea acoustic, li-motors tsa ultrasonic, jj

Lisebelisoa tsa piezoelectric li sebelisoa haholo ha ho etsoa li-transducers tsa ultrasonic, li-transducers tse tsamaeang ka tlas'a metsi, li-electroacoustic transducers, li-filter tsa ceramic, li-ceramic transformers, li-discriminator tsa ceramic, lijenereithara tse phahameng tsa motlakase, lisebelisoa tsa infrared, lisebelisoa tsa maqhubu a holim'a metsi, lisebelisoa tsa electro-optic, ho chesa le ho senya lisebelisoa, li-piezoelectric gyros, jj, ha li sebelisoe feela masimong a theknoloji e phahameng, empa le bophelong ba letsatsi le letsatsi ho sebeletsa batho le ho theha bophelo bo betere bakeng sa batho.

Ntoeng ea II ea Lefatše, li-ceramics tsa BaTiO3 li ile tsa sibolloa, 'me lisebelisoa tsa piezoelectric le ts'ebeliso ea tsona tsa etsa tsoelo-pele e kholo. Mmenano BaTiO3 phofo e nolofalletsa ho hlahisa BaTiO3 Ceramic e nang le thepa e tsoetseng pele haholo.

Qetellong ea lekholo la bo20 la lilemo, bo-rasaense ba lintho tse bonahalang ba tsoang lefats'eng lohle ba ile ba qala ho batlisisa lisebelisoa tse ncha tsa motlakase. Ka lekhetlo la pele, mohopolo oa lisebelisoa tsa nano o ile oa hlahisoa thutong ea lisebelisoa tsa piezoelectric, tse entseng hore lipatlisiso le nts'etsopele ea lisebelisoa tsa piezoelectric, sesebelisoa se sebetsang, li tobane le katleho e kholo, e bonts'itsoeng ka lisebelisoa. Phetoho ea ts'ebetso ke hore thepa ea mochini, thepa ea piezoelectric le thepa ea dielectric li ntlafalitsoe haholo. Ha ho pelaelo hore sena se tla ba le phello e ntle ts'ebetsong ea transducer.

Hajoale, mokhoa o ka sehloohong oa ho amohela mohopolo oa metara ea nano ho lisebelisoa tse sebetsang tsa piezoelectric ke ho ntlafatsa litšobotsi tse ling tsa lisebelisoa tsa piezoelectric (eketsa li-nanoparticles tse fapaneng ho etsa li-nano complexes ka lisebelisoa tsa piezoelectric) le (sebelisa li-piezoelectric nanopowders kapa Nanocrystals le polymers li entsoe ka thepa e entsoeng ka likarolo mekhoa e khethehileng) mekhoa e 2. Mohlala, lefapheng la lintho tse bonahalang la Thanh Ho University, molemong oa ho ntlafatsa polarization ea saturation le polarization ea mesaletsa ea lisebelisoa tsa letsopa tsa ferroelectric, Ag nanoparticles li ile tsa eketsoa ho hlophisa "nano-multiphase ferroelectric ceramics based on metal nanoparticles / ferroelectric ceramics"; Joalo ka nano alumina (AL2O3) / PZT,nano zirconium dioxide (ZrO2)/ PZT le lisebelisoa tse ling tsa nano composite ferroelectric ceramics ho fokotsa lisebelisoa tsa pele tsa ferroelectric k31 le ho eketsa ho thatafala ha fracture; lisebelisoa tsa nano piezoelectric le lipolisi tse kopaneng ho fumana lisebelisoa tsa nano piezoelectric composite. Lekhetlong lena re tla ithuta ho hlophisoa ha letsopa la piezoelectric ka ho kopanya powders ea nano piezoelectric le li-nano organic additives, ebe re ithuta ka liphetoho tsa thepa ea piezoelectric le thepa ea dielectric.

Re lebelletse ts'ebeliso e ntseng e eketseha ea lisebelisoa tsa nanoparticles ho li-piezoelectric ceramics!
