Mumhuri huru yezvinhu zvisingawanzo pasi,gadolinium oxide (Gd2O2)yave nyeredzi munharaunda yesainzi yemidziyo ine yakasarudzika yemuviri uye makemikari zvimiro uye yakakura mashandisirwo minda. Ichi chichena chehupfu hachisi chete nhengo yakakosha yeasingawanzo pasi oxides, asiwo chinhu chakakosha chinoshanda mukuvandudza kwesainzi yemazuva ano uye tekinoroji. Kubva pakufungidzira kwekurapa kusvika kune tekinoroji yesimba renyukireya, kubva kune magineti kusvika kune zvigadzirwa zvemaziso, gadolinium oxide iri kwese kwese, ichiratidza kukosha kwakasiyana kwezvinhu zvisingawanzo pasi.
1. Zvinhu zvakakosha zve gadolinium oxide
Gadolinium oxideinowanzoitika isingawanzo pasi oxide ine cubic crystal chimiro. Muchimiro chayo chekristaro, gadolinium ions neokisijeni ion zvinosanganiswa mune imwe nzvimbo yekuronga kuti iite yakagadzikana kemikari bond. Ichi chimiro chinopa gadolinium oxide nzvimbo yekunyunguduka inosvika 2350 ° C, ichibvumira kuti irambe yakagadzikana munzvimbo dzekushisa kwepamusoro.
Panyaya yemakemikari zvivakwa, gadolinium oxide inoratidza yakajairwa alkaline oxide maitiro. Inogona kuita nemaasidhi kuumba saiti inoenderana uye ine imwe hygroscopicity. Aya maitiro anoda yakakosha kuchengetedza uye kubata mamiriro egadolinium oxide panguva yekugadzirira zvinhu.
Panyaya yezvimiro zvemuviri, gadolinium oxide ine yakanakisa optical uye magineti zvivakwa. Iine high refractive index uye yakanaka transmittance chiedza munzvimbo inooneka chiedza, iyo inoisa hwaro hwekushandiswa kwayo mundima yemaziso. Panguva imwecheteyo, iyo 4f electron shell chimiro chegadolinium ion inopa iyo yakasiyana nemagnetic properties.

2. Core application nzvimbo dze gadolinium oxide
Mundima yezvokurapa, iyo inonyanya kukosha kushandiswa kwegadolinium oxide yakaita seyakabikwa yemagnetic resonance imaging (MRI) inosiyanisa vamiririri. Gadolinium complexes inogona kushandura zvakanyanya nguva yekuzorora yemapurotoni emvura, kuvandudza kusiyanisa kwekufungidzira, uye kupa mifananidzo yakajeka yekuongororwa kwechirwere. Ichi chishandiso chakakurudzira zvikuru kuvandudzwa kwehunyanzvi hwekufungidzira hwemazuva ano hwekurapa.
Mumunda wezvigadzirwa zvemagineti, gadolinium oxide chinhu kiyi mbishi yekugadzira zvinhu zvemagineti senge gadolinium iron garnet (GdIG). Zvishandiso izvi zvinoita basa rakakosha mumichina yemicrowave uye magneto-optical zvishandiso, uye zvinopa hwaro hwezvinhu zvekuvandudza tekinoroji yemazuva ano yekutaurirana.
Mune optical application, gadolinium oxide inoshandiswa zvakanyanya mu phosphors, laser materials, optical coatings uye mamwe minda nekuda kweakanakisa optical zvimiro. Kunyanya mukugadzirira kwepamusoro-refractive-index optical films, gadolinium oxide inoratidza zvakanakira zvakanakira.
Mune tekinoroji yesimba renyukireya, gadolinium oxide inoshandiswa sechinhu chekudzora simbi yemareactor enyukireya nekuda kweiyo yakakwira neutron absorption cross chikamu. Ichi chishandiso chakakosha zvikuru pakushanda kwakachengeteka kwemagetsi enyukireya.
3. Ramangwana rekuvandudza gadolinium oxide
Nekufambira mberi kwehunyanzvi hwekugadzirira, iyo synthesis nzira yegadolinium oxide yagara ichigadziriswa. Kubva pane yechinyakare yakasimba-chikamu chekuita nzira kusvika kune yepamusoro sol-gel nzira, kuvandudzwa kwegadziriro yekugadzirira kwakavandudza zvakanyanya kuchena uye kuita kwegadolinium oxide.
Mundima dzekushandisa dziri kubuda, gadolinium oxide inoratidza kugona kukuru. Musimba-nyika mwenje, quantum computing, kutonga kwezvakatipoteredza uye zvimwe zvinhu, vaongorori vari kuongorora mashandisirwo matsva egadolinium oxide. Ongororo idzi dzakavhura nzira nyowani dzekuvandudzwa kweramangwana gadolinium oxide.
Kubva pamaonero etarisiro yeindasitiri, nekukurumidza kusimudzira maindasitiri ari kusimukira akadai sesimba idzva nezvinhu zvitsva, kudiwa kwemusika kwegadolinium oxide kucharamba kuchikura. Kunyanya muminda yekugadzirwa kwepamusoro uye yekucheka-kumucheto tekinoroji, kukosha kwegadolinium oxide kuchawedzerwa.
Senhengo yakakosha yemhuri isingawanzo zvinhu zvepasi, kukosha kwegadolinium oxide hakungoratidzwi muhuwandu hwayo hwazvino hwemashandisirwo, asiwo mune zvisingaperi zvingangoitika mune ramangwana rekuvandudza tekinoroji. Kubva kuhutano hwekurapa kusvika kune tekinoroji yemagetsi, kubva pakukurukurirana kweruzivo kusvika pakuchengetedzwa kwezvakatipoteredza, gadolinium oxide iri kuita zvakakosha mukufambisira mberi kwesainzi yevanhu uye tekinoroji nehunhu hwayo hwakasiyana. Nekuenderera mberi kwekuvandudzwa kwesainzi yezvishandiso, gadolinium oxide ichapenya mune mamwe minda uye kuenderera mberi nengano chitsauko chezvinhu zvisingawanzo pasi.
