Piezoelectric yumbu abu ne mai aiki mai aiki-piezoelectric sakamako wanda zai iya canza makamashin inji da makamashin lantarki.Baya ga piezoelectricity, piezoelectric ceramics kuma suna da kaddarorin dielectric da elasticity.A cikin al'umma na zamani, kayan aikin piezoelectric, a matsayin kayan aiki na kayan aikin lantarki, suna taka muhimmiyar rawa a cikin manyan fasahohin fasaha.

Ferroelectric yumbu nau'in yumbu ne na piezoelectric wanda manyan halayensa sune:
(1) Akwai polarization na kwatsam a cikin takamaiman yanayin zafi.Lokacin da ya fi zafin Curie, polarization na lokaci-lokaci yana ɓacewa kuma lokacin ferroelectric yana canzawa zuwa lokacin paraelectric;
(2) kasancewar wani yanki;
(3) Lokacin da yanayin polarization ya canza, yanayin yanayin zafi na dielectric akai-akai yana canzawa sosai, kololuwa, kuma yana biyayya ga dokar Curie-Weiss;
(4) Ƙarfin polarization yana canzawa tare da ƙarfin filin lantarki da aka yi amfani da shi don samar da madauki na hysteresis;
(5) Dielectric akai-akai yana canzawa ba tare da layi ba tare da filin lantarki da aka yi amfani da shi;
(6) Samar da wutar lantarki ko nau'in lantarki a ƙarƙashin aikin filin lantarki

Barium titanate wani abu ne na fili na ferroelectric tare da babban dielectric akai-akai da ƙananan asarar dielectric.Yana daya daga cikin kayan da aka fi amfani dashi a cikin kayan lantarki na lantarki kuma an san shi da "ginshiƙan masana'antar yumbu na lantarki".

BATIO3tukwane bincike ne da haɓaka kayan yumbu masu balagagge marasa gubar piezoelectric tare da babban dielectric akai-akai, babban haɗaɗɗen haɗaɗɗiyar lantarki da ƙimar piezoelectric akai-akai, matsakaicin ingancin injin inji da ƙananan asarar dielectric.

A matsayin ferroelectric abu, barium titanate (BaTiO3) ne yadu amfani a muti-Layer yumbu capacitors, sonar, infrared radiation ganewa, hatsi iyaka yumbu capacitors, m zafin jiki coefficient thermal tukwane, da dai sauransu The m aikace-aikace al'amurran da aka sani da ginshikan lantarki. tukwane.Tare da haɓaka ƙananan na'urorin lantarki, masu nauyi, masu dogara da ƙananan na'urorin lantarki da kayan aikin su, buƙatun mai tsabta mai tsabta ultra-lafiya barium titanate foda yana zama mafi gaggawa.
