Mu muryango mugari wibintu bidasanzwe byisi,okiside ya gadolinium (Gd2O2)yahindutse inyenyeri mubikoresho siyanse hamwe nibintu byihariye byumubiri na chimique hamwe nibikorwa byinshi. Iyi poro yera ntabwo ari umunyamuryango wingenzi wa oxyde yisi idasanzwe, ahubwo ni nibikoresho byingenzi mubikorwa byiterambere rya siyansi nubuhanga bugezweho. Kuva amashusho yubuvuzi kugeza tekinoroji ya kirimbuzi, kuva mubikoresho bya magnetiki kugeza kubikoresho bya optique, okiside ya gadolinium iri hose, igaragaza agaciro kadasanzwe kwibikoresho bidasanzwe byubutaka.
1. Ibintu byingenzi bya okiside ya gadolinium
Okiside ya Gadoliniumni ubusanzwe isi idasanzwe ya oxyde ifite cubic kristal. Mu miterere yacyo ya kirisiti, ion ya gadolinium na ogisijeni ion byahujwe muburyo bwihariye kugirango bibe bihuza imiti ihamye. Iyi miterere itanga okiside ya gadolinium gushonga kugera kuri 2350 ° C, bigatuma iguma ihagaze neza mubushyuhe bwo hejuru.
Kubijyanye nimiterere yimiti, okiside ya gadolinium yerekana ibiranga okiside ya alkaline. Irashobora gukora hamwe na acide kugirango ikore umunyu uhuye kandi ifite hygroscopique. Ibi biranga bisaba kubika no gufata neza uburyo bwa okiside ya gadolinium mugihe cyo gutegura ibikoresho.
Kubijyanye nimiterere yumubiri, oxyde ya gadolinium ifite ibyiza bya optique na magnetique. Ifite indangagaciro ndende kandi yorohereza urumuri mu karere kagaragara, itanga umusingi wo kuyikoresha mu murima wa optique. Mugihe kimwe, 4f electron shell shell ya gadolinium ion itanga imiterere yihariye ya magneti.

2. Ibyingenzi bikoreshwa mubice bya okiside ya gadolinium
Mu rwego rwubuvuzi, ikoreshwa ryingenzi rya okiside ya gadolinium ni nkibikoresho fatizo byerekana amashusho ya magnetiki resonance yerekana amashusho (MRI). Uruganda rwa Gadolinium rushobora guhindura cyane igihe cyo kuruhuka kwa proton y'amazi, kunoza itandukaniro ryerekana amashusho, no gutanga amashusho asobanutse yo gusuzuma indwara. Iyi porogaramu yazamuye cyane iterambere rya tekinoroji yubuvuzi bugezweho.
Mu rwego rwibikoresho bya magneti, okiside ya gadolinium nigikoresho cyingenzi cyo gutegura ibikoresho bya magneti nka garnet ya gadolinium (GdIG). Ibi bikoresho bigira uruhare runini mubikoresho bya microwave nibikoresho bya magneto-optique, kandi bitanga umusingi wibikorwa byiterambere ryikoranabuhanga rigezweho ryitumanaho.
Mubikorwa bya optique, okiside ya gadolinium ikoreshwa cyane muri fosifore, ibikoresho bya laser, gutwika optique hamwe nizindi nzego bitewe nuburyo bwiza bwa optique. Cyane cyane mugutegura firime-optique ya firime optique, okiside ya gadolinium yerekana ibyiza byihariye.
Mu ikoranabuhanga ry’ingufu za kirimbuzi, okiside ya gadolinium ikoreshwa nkibikoresho byo kugenzura ibyuma bya nucleaire kubera igice kinini cyayo cya neutron. Iyi porogaramu ifite akamaro kanini kubikorwa byumutekano bya reaction za kirimbuzi.
3. Iterambere ry'ejo hazaza rya okiside ya gadolinium
Hamwe niterambere ryiterambere rya tekinoroji, uburyo bwa synthesis ya gadolinium oxyde bwakomeje kunozwa. Kuva muburyo gakondo bukomeye bwa reaction yuburyo bugera kuri sol-gel yateye imbere, kunoza gahunda yo gutegura byazamuye cyane isuku nimikorere ya oxyde ya gadolinium.
Mugihe kigaragara cyo gusaba, gadolinium oxyde yerekana ubushobozi bukomeye. Mu kumurika cyane, kubara kwant, kubara ibidukikije nibindi bice, abashakashatsi barimo gushakisha uburyo bushya bwa okiside ya gadolinium. Ubu bushakashatsi bwafunguye icyerekezo gishya cyiterambere rya kazole ya gadolinium.
Urebye ibyerekezo byinganda, hamwe niterambere ryihuse ryinganda zigenda zitera imbere nkingufu nshya nibikoresho bishya, isoko rya okiside ya gadolinium izakomeza kwiyongera. By'umwihariko mu bijyanye n’inganda zo mu rwego rwo hejuru n’ikoranabuhanga rigezweho, akamaro ka okiside ya gadolinium izarushaho kwiyongera.
Nkumunyamuryango wingenzi wumuryango wibintu bidasanzwe byisi, agaciro ka okiside ya gadolinium ntigaragarira gusa mubikorwa byinshi bigezweho, ariko no mubishoboka bitagira imipaka mugutezimbere ikoranabuhanga. Kuva ku buzima bw’ubuvuzi kugeza ku ikoranabuhanga ry’ingufu, kuva mu itumanaho ryamakuru kugeza kurengera ibidukikije, okiside ya gadolinium itanga umusanzu wingenzi mu guteza imbere ubumenyi n’ikoranabuhanga bya muntu hamwe n’imiterere yihariye. Hamwe niterambere ryiterambere ryibikoresho siyanse, okiside ya gadolinium rwose izamurika mumirima myinshi kandi ikomeze igice cyamamare cyibikoresho bidasanzwe byubutaka.
