Piezoelectric ceramic is a functional ceramic material-piezoelectric effect iyo inogona kushandura simba remagetsi uye simba remagetsi.Pamusoro pepiezoelectricity, piezoelectric ceramics zvakare ine dielectric zvimiro uye elasticity.Munzanga yemazuva ano, piezoelectric zvinhu, sezvinhu zvinoshanda zvekushandura kwe electromechanical, zvinoita basa rinokosha muminda yepamusoro-soro.

Ferroelectric ceramics imhando yepiezoelectric ceramics ane maitiro makuru ndeaya:
(1) Pane kungoerekana polarization mune imwe tembiricha renji.Kana yakakwira kupfuura tembiricha yeCurie, iyo polarization inongoerekana yanyangarika uye chikamu cheferroelectric chinoshanduka kuita paraelectric phase;
(2) kuvapo kwenzvimbo;
(3) Kana iyo polarization mamiriro achinja, dielectric inogara-temperature hunhu inoshanduka zvakanyanya, inokwira, uye inoteerera mutemo waCurie-Weiss;
(4) Iyo polarization intensity inoshanduka neyakashandiswa simba remunda wemagetsi kuita hysteresis loop;
(5) Dielectric inogara ichichinja zvisina tsarukano neyakaiswa magetsi munda;
(6) Kugadzira electrostriction kana electrostrictive strain pasi pechiito chemunda wemagetsi

Barium titanate iferroelectric compound material ine yakakwira dielectric nguva dzose uye yakaderera dielectric kurasikirwa.Icho chimwe chezvinhu zvakanyanya kushandiswa mumagetsi ekeramics uye inozivikanwa se "mbiru yemagetsi ceramic industry".

BaTIO3Ceramics kutsvagisa nekuvandudza kweyakakura-isina piezoelectric ceramic zvinhu zvine yakakwira dielectric inogara, hombe electromechanical coupling coefficient uye piezoelectric nguva dzose, yepakati mechanical quality factor uye diki dielectric kurasikirwa.

Sechinhu cheferroelectric, barium titanate (BaTiO3) inoshandiswa zvakanyanya mumuti-layer ceramic capacitors, sonar, infrared radiation kuona, zviyo muganhu ceramic capacitors, yakanaka tembiricha coefficient thermal ceramics, etc. Iyo yakafara tarisiro yekushandisa inozivikanwa sembiru dzemagetsi. Ceramics.Nekuvandudzwa kwezvidiki, zvisingaremi, zvinovimbika uye zvitete zvemagetsi zvigadzirwa uye zvikamu zvazvo, kudiwa kwepamusoro-kuchena kwepamusoro-soro barium titanate poda kuri kuramba kuchiwedzera nekukurumidza.
