I-Piezoelectric ceramic yinto esebenzayo ye-ceramic material-piezoelectric effect enokuguqula amandla omatshini kunye namandla ombane.Ukongeza kwi-piezoelectricity, ii-ceramics ze-piezoelectric nazo zineempawu ze-dielectric kunye ne-elasticity.Kuluntu lwanamhlanje, izinto ze-piezoelectric, njengezinto ezisebenzayo zokuguqulwa kwe-electromechanical, zidlala indima ebalulekileyo kwiinkalo zobugcisa obuphezulu.
Iiseramikhi zeFerroelectric luhlobo lweeseramikhi zepiezoelectric ezineempawu eziphambili ezi:
(1) Kukho i-polarization ezenzekelayo kuluhlu oluthile lobushushu.Xa iphezulu kunobushushu beCurie, i-polarization ezenzekelayo iyanyamalala kwaye isigaba se-ferroelectric sitshintsha sibe yi-paraelectric phase;
(2) ubukho bommandla;
(3) Xa imeko ye-polarization itshintsha, i-dielectric constant-temperature ye-dielectric itshintsha kakhulu, iphakame, kwaye ithobela umthetho kaCurie-Weiss;
(4) I-polarization intensity intensity itshintsha ngamandla ombane asetyenzisiweyo ukwenza i-hysteresis loop;
(5) Ukutshintsha kwe-dielectric rhoqo ngokungafaniyo nentsimi yombane esetyenzisiweyo;
(6) Ukuvelisa i-electrostriction okanye i-electrostrictive strain phantsi kwesenzo sommandla wombane
I-Barium titanate yinto edibeneyo ye-ferroelectric ene-dielectric rhoqo kunye nelahleko ephantsi ye-dielectric.Yenye yezona zinto zisetyenziswa kakhulu kwiiseramics ze-elektroniki kwaye yaziwa ngokuba "yintsika yoshishino lwe-ceramic yombane".
I-BATIO3iiseramics luphando kunye nophuhliso lwezixhobo zeseramikhi zepiezoelectric ezikhulileyo ezingenalo ilothe ezine-dielectric engaguqukiyo, i-electromechanical coefficient yokudibanisa kunye ne-piezoelectric engaguqukiyo, umgangatho ophakathi koomatshini kunye nelahleko encinci ye-dielectric.
Njengemathiriyeli ye-ferroelectric, i-barium titanate (i-BaTiO3) isetyenziswa ngokubanzi kwi-muti-layer ceramic capacitors, i-sonar, ubhaqo lwe-infrared radiation, i-gray boundary ye-ceramic capacitors, i-coefficient yobushushu be-thermal ceramics, njl. iiseramikhi.Ngokuphuhliswa kwezixhobo ze-elektroniki ezincinci, ezikhaphukhaphu, ezithembekileyo kunye nezincinci kunye namacandelo azo, imfuno ye-high-purity ultra-fine barium titanate powder iya ingxamiseka ngakumbi.
