O le Barium titanate e le gata o se vailaʻau vailaʻau taua, ae ua avea foʻi ma se tasi o mea faʻapitoa e manaʻomia ile pisinisi eletise.I le faiga o le BaO-TiO2, i le faaopoopo atu i le BaTiO3, o loʻo i ai le tele o mea faʻapipiʻi e pei o Ba2TiO4, BaTi2O5, BaTi3O7 ma BaTi4O9 faʻatasi ai ma vaʻaiga eseese o le barium-titanium.Faatasi ai ma i latou, o le BaTiO3 e sili ona aoga, ma o lona igoa vailaʻau o le barium metatitanate, lea e lauiloa foi o le barium titanate.

1. O mea tau kemisi onano barium titanate(nano BaTiO₃)

1.1.O le Barium titanate o se paʻepaʻe paʻepaʻe ma se mea faʻafefe e tusa ma le 1625 ° C ma le mamafa faʻapitoa o le 6.0.E soluble i totonu o le sulfuric acid concentrated, hydrochloric acid ma hydrofluoric acid, ae le mafai ona solu i le vevela dilute nitric acid, vai ma alkali.E lima ituaiga o suiga tioata: foliga tioata hexagonal, foliga tioata kupita, foliga tioata tetragonal, foliga tioata trigonal ma foliga tioata orthorhombic.O le mea sili ona taatele o le tioata vaega tetragonal.A oʻo atu le BaTiO2 i se eletise eletise maualuga, o le a faʻaauau pea le faʻaogaina o aafiaga i lalo ole Curie point ole 120°C.Polarized barium titanate e lua mea taua: ferroelectricity ma piezoelectricity.

1.2.O le dielectric faifai pea e matua maualuga lava, lea e maua ai le nano barium titanate ni mea faʻapitoa dielectric, ma ua avea ma mea taua i le ogatotonu o vaega taʻavale maualuga.I le taimi lava e tasi, o loʻo faʻaaogaina foi le eletise malosi i le faʻalauteleina o ala o faasalalauga, faʻasologa o taimi ma mea e teu ai.

1.3.E lelei le piezoelectricity.O le Barium titanate e a'afia i le ituaiga perovskite ma e lelei le piezoelectricity.E mafai ona faʻaaogaina i suiga eseese o le malosi, liua leo, faʻaliliuga faʻailoga ma oscillation, microwave ma sensors e faʻavae i luga o piezoelectric faʻatusa tutusa.fasi.

1.4.Ferroelectricity o se tulaga talafeagai mo le i ai o isi aafiaga.O le amataga o le ferroelectricity e sau mai le polarization fa'afuase'i.Mo ceramics, o le piezoelectric, pyroelectric, ma photoelectric aafiaga uma mai le polarization mafua mai polarization tuusaʻo, vevela poʻo le eletise.

1.5.Aafiaga lelei o le vevela.O le a'afiaga PTC e mafai ona mafua ai se suiga o le ferroelectric-paraelectric i mea i totonu o le tele o le sefulu tikeri maualuga atu nai lo le vevela Curie, ma le maualuga o le vevela o le potu e faʻateleina i le tele o poloaiga o le tele.I le faʻaaogaina o lenei faʻatinoga, o mea e faʻaogaina ai le vevela na saunia ma le BaTiO3 nano paʻu ua faʻaaogaina lautele i masini faʻapipiʻi telefoni feaveaʻi, masini afi afi, masini faʻamalo mo TV lanu, faʻapipiʻi mo pusa pusaaisa, masini vevela, ma puipui vevela, ma isi..

2. Faʻaaogaina o le barium titanate nano

O le Barium titanate o le lona tolu lea na maua mai le tino eletise malosi ina ua maeʻa le masima faʻalua o le potassium sodium tartrate ma le tino eletise malosi o le calcium phosphate system.Talu ai ona o se ituaiga fou o le tino eletise malosi e le mafai ona faʻaaogaina i le vai ma e lelei le vevela, e tele lona aoga aoga, aemaise lava i tekinolosi semiconductor ma tekinolosi faʻapipiʻi.

Mo se faʻataʻitaʻiga, o ona tioata o loʻo i ai le maualuga o le dielectric tumau ma le vevela fesuiaiga, ma o loʻo faʻaaogaina lautele e pei o le laʻititi-volume, microcapacitors tele-mafai ma vaega tau taui.

E mautu mea tau eletise.E mafai ona faʻaaogaina e gaosia ai vaega nonlinear, dielectric amplifiers ma mea e manatua ai komepiuta faaeletonika (manatua), ma isi E iai foʻi mea piezoelectric o le liua electromechanical, ma e mafai ona faʻaaogaina e avea o se vaega mea mo masini e pei o pusa faʻamaufaʻailoga, masini suʻesuʻe vai eleele. , ma masini eletise ultrasonic.

E le gata i lea, e mafai foi ona faʻaaogaina e gaosia ai le eletise eletise, inverters, thermistors, photoresistors ma mea manifinifi ata tifaga tekonolosi.

Nano barium titanateo le mea masani mata o mea eletise eletise, ua taʻua o le pou o le eletise eletise eletise, ma o se tasi foi o mea sili ona faʻaaogaina ma sili ona taua i mea faʻaeletoroni.I le taimi nei, ua faʻaaogaina ma le manuia i le PTC thermistors, multilayer ceramic capacitors (MLCC), pyroelectric element, piezoelectric ceramics, sonar, infrared radiation detection elements, crystal ceramic capacitors, electro-optic display panels, mea manatua, mea semiconductor, electrostatic transformers. , amplifiers dielectric, liliu taimi, manatua, polymer matrix composite ma coatings, ma isi.

Faatasi ai ma le atinaʻeina o mea tau eletise, o le faʻaaogaina o le barium titanate o le a sili atu ona lautele.

3. Nano barium titanate gaosi oloa-Hongwu Nano

Guangzhou Hongwu Material Technology Co., Ltd. o loʻo i ai se tuʻufaʻatasiga umi ma mautu o paʻu sili ona lelei nano barium titanate i vaega ma tau faʻatauvaʻa.O lo'o avanoa uma vaega kupita ma tetragonal, fa'atasi ai ma le tele o vaega 50-500nm.
