Barium titanate ba kawai samfurin sinadari mai kyau ba ne kawai, amma kuma ya zama ɗaya daga cikin manyan albarkatun da babu makawa a cikin masana'antar lantarki.A cikin tsarin BaO-TiO2, ban da BaTiO3, akwai mahadi da yawa kamar Ba2TiO4, BaTi2O5, BaTi3O7 da BaTi4O9 tare da ma'aunin barium-titanium daban-daban.Daga cikin su, BaTiO3 yana da mafi girman darajar aiki, kuma sunansa na sinadarai shine barium metatitanate, wanda kuma aka sani da barium titanate.

1. Physicochemical Properties nanano barium titanate(na BaTiO₃)

1.1.Barium titanate wani farin foda ne mai narkewa na kusan 1625 ° C da takamaiman nauyi na 6.0.Yana narkewa a cikin sulfuric acid da aka tattara, hydrochloric acid da hydrofluoric acid, amma ba a iya narkewa a cikin zafi mai tsarma nitric acid, ruwa da alkali.Akwai nau'ikan gyare-gyaren kristal guda biyar: nau'in crystal hexagonal, nau'in kristal mai siffar sukari, nau'in crystal tetragonal, nau'in crystal trigonal da siffar kristal orthorhombic.Mafi na kowa shine tetragonal lokaci crystal.Lokacin da BaTiO2 ya kasance ƙarƙashin babban filin lantarki na yanzu, ci gaba da tasirin polarization zai faru a ƙasa da ma'aunin Curie na 120°C.Polarized barium titanate yana da mahimman kaddarorin guda biyu: ferroelectricity da piezoelectricity.

1.2.Dielectric akai-akai yana da girma sosai, wanda ke sa nano barium titanate yana da kaddarorin dielectric na musamman, kuma ya zama wani abu mai mahimmanci a tsakiyar manyan abubuwan kewayawa.A lokaci guda kuma, ana amfani da wutar lantarki mai ƙarfi wajen haɓaka kafofin watsa labaru, daidaita mitar da na'urorin ajiya.

1.3.Yana da kyau piezoelectricity.Barium titanate nasa ne na nau'in perovskite kuma yana da kyau piezoelectricity.Ana iya amfani dashi a cikin jujjuyawar kuzari daban-daban, jujjuya sauti, jujjuya sigina da oscillation, microwave da na'urori masu auna firikwensin dangane da da'irori daidai na piezoelectric.guda.

1.4.Ferroelectricity shine yanayin da ake buƙata don wanzuwar sauran tasirin.Asalin ferroelectricity ya fito ne daga polarization na kwatsam.Don yumbu, piezoelectric, pyroelectric, da kuma tasirin hoto duk sun samo asali ne daga polarization wanda ke haifar da polarization ba tare da bata lokaci ba, zazzabi ko filin lantarki.

1.5.Tasirin madaidaicin zafin jiki.Tasirin PTC na iya haifar da sauye-sauyen lokaci na ferroelectric-paraelectric a cikin kayan cikin kewayon dubun digiri sama da zafin Curie, kuma juriya na zafin dakin yana ƙaruwa sosai ta umarni da yawa na girma.Yin amfani da wannan aikin, kayan aikin yumbu masu zafi da aka shirya tare da BaTiO3 nano foda an yi amfani da su sosai a cikin na'urorin tsaro na tarho masu sarrafa shirye-shiryen, injin motar mota, masu ɗaukar hoto ta atomatik don TVs masu launi, masu farawa don compressors na firiji, firikwensin zafin jiki, da masu kare zafi, da dai sauransu.

2. Aikace-aikacen barium titanate nano

Barium titanate shine na uku da aka gano mai ƙarfi mai ƙarfi bayan tsarin gishiri biyu na potassium sodium tartrate da kuma ƙarfin lantarki na tsarin calcium phosphate.Domin sabon nau'in jikin lantarki ne mai ƙarfi wanda ba shi da narkewa a cikin ruwa kuma yana da kyakkyawan juriya na zafi, yana da ƙima mai mahimmanci, musamman a fasahar semiconductor da fasahar insulation.

Misali, lu'ulu'un sa suna da madaidaicin dielectric akai-akai da sigogi masu canzawa na thermal, kuma ana amfani da su sosai azaman ƙaramin ƙarami, babban ƙarfin microcapacitors da abubuwan ramuwa na zafin jiki.

Yana da kaddarorin lantarki masu tsayayye.Ana iya amfani da shi don kera abubuwan da ba na layi ba, dielectric amplifiers da abubuwan ƙwaƙwalwar ajiyar kwamfuta na lantarki (ƙwaƙwalwar ajiya), da dai sauransu. Hakanan yana da kaddarorin piezoelectric na juyawa na lantarki, kuma ana iya amfani dashi azaman kayan aikin na'urori irin su harsashin mai kunna rikodin, na'urorin gano ruwan ƙasa. , da ultrasonic janareta.

Bugu da ƙari, ana iya amfani da ita don kera masu canza wutar lantarki, inverters, thermistors, photoresistors da kayan aikin fasaha na lantarki na bakin ciki.

Nano barium titanateshi ne ainihin albarkatun kayan yumbu na lantarki, wanda aka sani da ginshiƙin masana'antar yumbu na lantarki, kuma ɗayan mafi yawan amfani da kayan da aka fi amfani da su a cikin yumbu na lantarki.A halin yanzu, an samu nasarar amfani da shi a cikin PTC thermistors, multilayer ceramic capacitors (MLCC), pyroelectric abubuwa, piezoelectric ceramics, sonar, infrared radiation gano abubuwa, crystal yumbu capacitors, electro-optic nuni panels, memory kayan, semiconductor kayan, electrostatic gidajen wuta. , Dielectric amplifiers, mitar converters, memories, polymer matrix composites da coatings, da dai sauransu.

Tare da ci gaban masana'antar lantarki, yin amfani da barium titanate zai fi girma.
