I-Piezoelectric ceramic iwumphumela osebenzayo we-ceramic material-piezoelectric ongaguqula amandla emishini namandla kagesi.Ngaphezu kwe-piezoelectricity, i-piezoelectric ceramics nayo inezakhiwo ze-dielectric kanye nokunwebeka.Emphakathini wanamuhla, izinto ze-piezoelectric, njengezinto ezisebenzayo zokuguqulwa kwe-electromechanical, zidlala indima ebalulekile emikhakheni yobuchwepheshe obuphezulu.

I-Ferroelectric ceramics iwuhlobo lwe-piezoelectric ceramics izici zayo eziyinhloko ziyi:
(1) Kukhona ukuhlukaniswa okuzenzakalelayo ebangeni elithile lokushisa.Uma iphakeme kunezinga lokushisa le-Curie, i-polarization ezenzakalelayo iyanyamalala futhi isigaba se-ferroelectric sishintsha sibe yisigaba se-paraelectric;
(2) ukuba khona kwesizinda;
(3) Uma isimo se-polarization sishintsha, isici se-dielectric-temperature esingaguquki sishintsha kakhulu, siphakame, futhi sithobele umthetho kaCurie-Weiss;
(4) Ukuqina kwe-polarization kuyashintsha ngamandla enkundla kagesi asetshenzisiwe ukuze kwakheke iluphu ye-hysteresis;
(5) I-dielectric njalo ishintsha ngokungahambisani nendawo kagesi esetshenzisiwe;
(6) Ukukhiqiza i-electrostriction noma i-electrostrictive strain ngaphansi kwesenzo senkundla kagesi

I-Barium titanate iyi-ferroelectric compound material ene-dielectric ephezulu engaguquki kanye nokulahlekelwa okuphansi kwe-dielectric.Ingenye yezinto ezisetshenziswa kakhulu kuma-ceramics kagesi futhi yaziwa ngokuthi "insika yemboni ye-ceramic kagesi".

I-BATIO3izitsha zobumba ziwucwaningo nokuthuthukiswa kwezinto zobumba ezivuthiwe ezingenamthofu ze-piezoelectric ezine-dielectric engaguquki, i-coefficient enkulu ye-electromechanical coupling kanye ne-piezoelectric engaguquki, isici sekhwalithi yomshini omaphakathi kanye nokulahlekelwa okuncane kwe-dielectric.

Njengempahla ye-ferroelectric, i-barium titanate (BaTiO3) isetshenziswa kakhulu kuma-muti-layer ceramic capacitor, i-sonar, ukutholwa kwemisebe ye-infrared, ama-ceramic capacitor omngcele wokusanhlamvu, izitsha zobumba ezishisayo ezishisayo, njll. Amathemba ohlelo olubanzi aziwa njengezinsika ze-elekthronikhi. izitsha zobumba.Ngokuthuthukiswa kwemishini kagesi emincane, engasindi, ethembekile nezacile kanye nezingxenye zayo, isidingo se-high-purity ultra-fine barium titanate powder siya ngokuya siphuthuma.
