M'banja lalikulu la zinthu zapadziko lapansi zapadziko lapansi,Gadolinium oxide (GD2O2)yakhala nyenyezi mu zinthu za sayansi ya sayansi yomwe ili ndi zinthu zake zapadera komanso zamankhwala ndi magawo ogwiritsira ntchito mankhwala. Mpweya woyera uwu sikuti ndi gawo lofunikira lokhalokha lomwe anthu osowa kwambiri padziko lapansi, komanso ndi zinthu zofunika kwambiri pakupanga sayansi ndi ukadaulo. Kuchokera kuzama zamankhwala ku magetsi a nyukiliya, kuchokera ku zida zamagetsi ku zida zowoneka bwino, gadolinium oxitiiti ali paliponse, akuwonetsa kufunika kwapadera kwa zida zapadziko lapansi.
1. Zoyambira zoyambira za gadolinium oxide
Gadolinium oxidendi lolamulira loipa kwambiri kwa oxide ndi mawonekedwe a cubic. Mu mawonekedwe ake a kristalo, ma ayolininium a ion ndi oxyulinium ma ions amaphatikizidwa munthawi inayake kuti apange mgwirizano wokhazikika. Kapangidwe kameneka kamapereka gadolinium oxide malo osungunuka mpaka 2350 ° C, kuloleza kuti ikhale yotseka mu kutentha kwambiri.
Pankhani ya mankhwala, gadolinium oxide wamba ma oxide ma oxide. Itha kuchitira ma asidi kuti apange mchere wolingana ndipo ali ndi hygrosophicity. Makhalidwewa amafunikira malongosoledwe apadera ndi kusamalira zinthu za gadolinium oxide pokonzekera zinthu.
Pankhani ya zinthu zakuthupi, gadolinium oxide imakhala ndi mitengo yabwino kwambiri komanso yamagnetica. Ili ndi njira yotsimikizika yayikulu komanso yopepuka bwino m'dera lowoneka bwino, lomwe limayikira maziko a ntchito yake mu munda wamaso. Nthawi yomweyo, kapangidwe ka magetsi kwa gadolinium ion kumapereka mphamvu yamatsenga yapadera.

2. Madera ogwiritsa ntchito a Gadolinium oxide
Mu gawo la zamankhwala, kugwiritsa ntchito kofunikira kwambiri kwa gadolinium oxide kuli ngati zinthu zopangira maginito a maginito (MRI). Mapulogalamu a gadolinium amatha kusintha nthawi yopumira ya ma proton, kusintha mawonekedwe ofananira, ndikupereka zithunzi zowoneka bwino pakuzindikira matenda. Izi zidalimbikitsa kwambiri kukula kwaukadaulo wamakono wolingalira zamankhwala.
Mu gawo la zida zamagetsi, gadolinium oxide ndi chinthu chofunikira kwambiri pokonzekera zida za maginito monga gadolinium in. Zipangizozi zimagwira ntchito yofunika ku zida za microwave ndi zida zamatsenga, ndipo zimapereka maziko a ukadaulo woyankhulidwa ndi zamakono.
M'mapulogalamu a m'maso, gadolinium oxide amagwiritsidwa ntchito kwambiri ku Phossor, zida za laser, zokutira zowoneka bwino ndi minda ina chifukwa cha zovuta zabwino kwambiri. Makamaka pokonzekera mafilimu owoneka bwino-ady, gadolinium oxide amawonetsa zabwino zapadera.
Muukadaulo wa nyukiliya, gadolinium oxide amagwiritsidwa ntchito ngati ndodo yowongolera ya nyukiliya chifukwa cha ma tatta a toutron a neutron. Izi ndizofunikira kwambiri pakugwira ntchito moyenera kwa nyukiliya.
3.. Kukula Kwachilendo kwa Gadolinium Oxide
Ndi kupita patsogolo kwaukadaulo wokonzekera njira ya Gadolinium oxide yakonzedwa mosalekeza. Kuchokera pakukonzekera gawo lokhazikika kwa njira yotsogola, kusintha kwa njira yokonzekera kwathandiza kwambiri kuyera ndi magwiridwe antchito a gadolinium oxide.
Pamagawo otuluka, gadolinium oxide akuwonetsa kupambana kwakukulu. M'magetsi olimba, kuchuluka kwa mabungwe azachilengedwe komanso zochitika zina, ofufuza akufufuza ntchito zatsopano za gadolinium oxide. Zojambulazi zatsegula njira zatsopano za kukula kwa gadolinium oxide.
Kuchokera pakuyembekeza mafakitale, chifukwa cha kukula kwa mafakitale omwe ali ndi mphamvu monga zida zatsopano ndi zinthu zatsopano, kufunikira kwa gadolinium oxitimu kudzakula. Makamaka mu minda yopanga malekezero opanga ndi kudula m'mphepete mwa nyanja, kufunikira kwa Gadoluinium oxide kumakulitsidwanso.
Monga munthu wofunika kwambiri wa banja lakuthupi lapadziko lapansi, mtengo wa Gadolinium oxide samangowoneka pamapulogalamu osiyanasiyana, komanso m'njira zopanda malire m'ukadaulo wa technological. Kuchokera pakuchipatala zaukadaulo, kuchokera ku kulumikizana kwamphamvu ku chitetezo cha chilengedwe, Gadolinium oxide akupanga zopereka zofunika kwambiri popititsa patsogolo ukadaulo wa anthu ndi ukadaulo wokhala ndi zida zapadera. Ndi chitukuko mosalekeza a sayansi, gadolinium oxile adzawala kwambiri m'minda yambiri ndikupitiliza mutu wa nthano wazinthu zapadziko lapansi.
