ʻO ka piezoelectric ceramic kahi mea hana ceramic material-piezoelectric hopena hiki ke hoʻololi i ka ikehu mechanical a me ka ikehu uila.Ma kahi o ka piezoelectricity, loaʻa i nā ceramics piezoelectric nā waiwai dielectric a me ka elasticity.I loko o ka nohona hou, nā mea piezoelectric, e like me nā mea hana no ka hoʻololi electromechanical, pāʻani i kahi hana koʻikoʻi i nā kula kiʻekiʻe.

ʻO Ferroelectric ceramics kahi ʻano o ka piezoelectric ceramics nona nā hiʻohiʻona nui:
(1) Aia ka polarization maʻamau i kekahi pae wela.Ke ʻoi aku ka kiʻekiʻe ma mua o kahi mahana Curie, nalowale ka polarization kuʻuna a hoʻololi ka pae ferroelectric i kahi pae paraelectric;
(2) ka noho ʻana o kahi kikowaena;
(3) Ke hoʻololi ka mokuʻāina polarization, hoʻololi nui ke ʻano o ka wela mau dielectric, piʻi, a hoʻolohe i ke kānāwai Curie-Weiss;
(4) Hoʻololi ka ikaika o ka polarization me ka ikaika o ke kahua uila e hana i kahi loop hysteresis;
(5) Hoʻololi ʻole ka dielectric mau me ke kahua uila i hoʻohana ʻia;
(6) Ka hana ʻana i ka electrostriction a i ʻole electrostrictive strain ma lalo o ka hana a kahi kahua uila

ʻO ka Barium titanate kahi mea hoʻohui ferroelectric me ke kiʻekiʻe dielectric mau a me ka haʻahaʻa dielectric nalowale.ʻO ia kekahi o nā mea i hoʻohana nui ʻia i nā seramika uila a ua ʻike ʻia ʻo ia ka "pou o ka ʻoihana ceramic electronic".

BaTIO3ʻO nā keramika ka noiʻi a me ka hoʻomohala ʻana i nā mea paʻa piezoelectric piezoelectric ʻoi loa me ke kiʻekiʻe dielectric mau, ka nui electromechanical coupling coefficient a me ka piezoelectric mau, medium mechanical quality factor a me ka liʻiliʻi dielectric poho.

Ma keʻano he mea ferroelectric, barium titanate (BaTiO3) hoʻohana nui ʻia i ka muti-layer ceramic capacitors, sonar, infrared radiation detection, grain boundary ceramic capacitors, positive temperature coefficient thermal ceramics, etc. seramika.Me ka hoʻomohala ʻana o nā mea uila liʻiliʻi, māmā, hilinaʻi a lahilahi a me kā lākou mau ʻāpana, ʻoi aku ka wikiwiki o ka noi no ka pauka barium titanate ultra-fine ultra-fine.
