Gukoresha ifu ya scandium Sc2O3 ifu

Gukoresha okiside ya scandium

Imiti ya chimique yaokisideni Sc2O3. Ibyiza: Umweru ukomeye. Hamwe nububiko bwubutaka budasanzwe sesquioxide. Ubucucike 3.864. Gushonga ingingo 2403 ℃ 20 ℃. Kudashonga mumazi, gushonga muri acide ishyushye. Itegurwa no kubora ubushyuhe bwumunyu wa scandium. Irashobora gukoreshwa nkibikoresho byo guhumeka kubice bya semiconductor. Kora lazeri ikomeye hamwe nuburebure bwumurongo, ibisobanuro bihanitse bya TV imbunda ya elegitoronike, itara ryicyuma, nibindi.

Scandium oxyde (Sc2O3) nimwe mubicuruzwa byingenzi bya scandium. Imiterere yumubiri na chimique bisa nibya oxyde yisi idasanzwe (nka La2O3, Y2O3 na Lu2O3, nibindi), kuburyo uburyo bwo kubyaza umusaruro mukubyara burasa cyane. Sc2O3 irashobora kubyara ibyuma bya Scandium (sc), umunyu utandukanye (ScCl3, ScF3, ScI3, Sc2 (C2O4) 3, nibindi) hamwe na aliyo ya scandium itandukanye (Al-Sc, Al-Zr-Sc). Ibicuruzwa bya scandium bifite agaciro ka tekiniki nibikorwa byiza byubukungu.Sc2O3 yakoreshejwe cyane murialuminium, isoko yumucyo wamashanyarazi, laser, catalizator, activateur, ceramics, icyogajuru nibindi kubera ibiranga. Kugeza ubu, imiterere ya Sc2O3 mubijyanye na alloy, isoko yumucyo wamashanyarazi, catalizator, activate na ceramics mubushinwa ndetse nisi byasobanuwe nyuma.

(1) ikoreshwa ryumuti

Kugeza ubu, Al-Sc ivanze ikozwe muri Sc na Al ifite ibyiza byubucucike buke (SC = 3.0g / cm3, Al = 2.7g / cm3, imbaraga nyinshi, ubukana bwinshi, plastike nziza, kurwanya ruswa ikomeye hamwe nubushyuhe bwumuriro, nibindi rero, yakoreshejwe neza mubice byubatswe bya misile, icyogajuru, indege, amamodoka nubwato, hanyuma buhoro buhoro ihinduka mubasivili, nkibikoresho byimikino (umupira wamaguru na baseball) Ifite ibiranga hejuru imbaraga, gukomera cyane nuburemere bworoshye, kandi bifite agaciro gakomeye.

Scandium igira uruhare runini rwo guhindura no gutunganya ingano muri alloy, biganisha ku gushiraho ubwoko bushya bwa Al3Sc nubwiza buhebuje. Al-Sc alloy yakoze urukurikirane rw'uruhererekane rw'uruvange, nk'urugero, Uburusiya bugeze ku bwoko 17 bw'uruhererekane rwa Al-Sc, kandi Ubushinwa nabwo bufite ibivange byinshi (nka Al-Mg-Sc-Zr na Al-Zn-Mg-Sc alloy). Ibiranga ubu bwoko bwimvange ntibishobora gusimburwa nibindi bikoresho, bityo rero uhereye kumajyambere, Iterambere ryimikorere hamwe nibishoboka ni byiza, kandi biteganijwe ko bizahinduka ikintu kinini mugihe kizaza. Kurugero, Uburusiya bwateje imbere umusaruro kandi butera imbere byihuse kubice byubatswe byoroheje, kandi Ubushinwa bwihutisha ubushakashatsi no kubukoresha, cyane cyane mu kirere no mu ndege.

(2) ikoreshwa ryibikoresho bishya bitanga amashanyarazi

ByeraSc2O3yahinduwe muri ScI3, hanyuma ikorwa mubisekuru bishya bya gatatu bitanga amashanyarazi hamwe na NaI, byatunganyirijwe mu itara rya scandium-sodium halogen yo kumurika (hafi 0.1mg ~ 10mg y'ibikoresho bya Sc2O3≥99% byakoreshejwe kuri buri tara. Munsi. igikorwa cyumubyigano mwinshi, umurongo wa scandium ni ubururu naho umurongo wa sodiumi ni umuhondo, kandi amabara yombi arafatanya kugirango atange urumuri rwegereye urumuri rwizuba.Umucyo ufite ibyiza byo kumurika cyane, ibara ryiza, kuzigama ingufu, kuramba hamwe nimbaraga zikomeye zica imbaraga.

(3) Gukoresha ibikoresho bya laser

Gadolinium gallium scandium garnet (GGSG) irashobora gutegurwa wongeyeho Sc2O3≥ 99.9% muri GGG, kandi ibiyigize ni ubwoko bwa Gd3Sc2Ga3O12. Imbaraga zohereza imyuka ya lazeri ya gatatu yakozwe muri yo irikubye inshuro 3.0 kurenza iya lazeri ifite ubunini bumwe, igeze ku gikoresho kinini kandi cyoroheje cya lazeri, cyongera imbaraga zo gusohora lazeri no kunoza imikorere ya laser . Mugihe utegura kristu imwe, Buri giciro ni 3kg ~ 5kg, kandi hafi 1.0kg yibikoresho fatizo hamwe na Sc2O3≥99.9% byongeweho. Kugeza ubu, ubu bwoko bwa lazeri bukoreshwa cyane mu buhanga bwa gisirikare, kandi bugenda busunikwa buhoro buhoro mu nganda za gisivili. Urebye iterambere, rifite amahirwe menshi mugukoresha igisirikare nabasivili mugihe kizaza.

(4) ikoreshwa ryibikoresho bya elegitoroniki

Sc2O3 yuzuye irashobora gukoreshwa nka okiside ya cathode ikora kuri cathode electron imbunda yamabara ya TV yerekana amashusho hamwe ningaruka nziza. Shira igipande cya Ba, Sr na Ca oxyde hamwe nubunini bwa milimetero imwe kuri cathode yigituba cyamabara, hanyuma ukwirakwiza urwego rwaSc2O3n'ubugari bwa milimetero 0.1 kuri yo. Muri cathode yumurongo wa oxyde, Mg na Sr bifata hamwe na Ba, biteza imbere kugabanuka kwa Ba, kandi electron zasohotse zirakora cyane, zitanga electron nini nini, zituma fosifore isohora urumuri. Ugereranije na cathode idafite Sc2O3. , irashobora kongera ubucucike bwikubye inshuro 4, bigatuma ishusho ya TV isobanuka neza kandi ikongerera ubuzima bwa cathode inshuro 3. Umubare wa Sc2O3 ukoreshwa kuri buri cathode ya santimetero 21 utera imbere ni 0.1mg Kugeza ubu, iyi cathode yakoreshejwe mu bihugu bimwe na bimwe ku isi, nk'Ubuyapani, bishobora kuzamura ubushobozi bwo guhangana ku isoko no guteza imbere igurishwa rya televiziyo.
