I totonu o le aiga tele o elemene o le eleele e le masani ai,gadolinium oxide (Gd2O2)ua avea ma se fetu i le sosaiete faasaienisi mea ma ona tulaga tulaga ese faaletino ma vailaau ma fanua faaaogaina lautele. O lenei mea paʻepaʻe paʻepaʻe e le gata o se sui taua o oxides eleele e le masani ai, ae o se mea taua tele i le atinaʻeina o saienisi ma tekinolosi faʻaonaponei. Mai faʻataʻitaʻiga faʻafomaʻi i tekonolosi malosi faaniukilia, mai mea maneta i masini mata, gadolinium oxide i soʻo se mea, e faʻaalia ai le tulaga ese o mea e le masani ai le lalolagi.
1. O mea taua o le gadolinium oxide
Gadolinium oxideose eleele oxide masani masani ma se fausaga tioata kupita. I totonu o lona fausaga tioata, gadolinium ions ma le okesene ua tuʻufaʻatasia i se faʻalapotopotoga faʻapitoa faʻapitoa e fausia ai se fusi faʻamalosi mau. O lenei fausaga e tuʻuina atu ai le gadolinium oxide se mea faʻafefeteina e oʻo atu i le 2350 ° C, faʻatagaina e tumau mautu i siosiomaga maualuga vevela.
I tulaga o vailaʻau, o le gadolinium oxide o loʻo faʻaalia uiga masani o le alkaline oxide. E mafai ona tali atu i acids e fausia ai masima tutusa ma e iai lona hygroscopicity. O nei uiga e manaʻomia ai le teuina ma le faʻaogaina o tulaga mo le gadolinium oxide i le taimi o sauniuniga.
I tulaga o mea faʻaletino, o le gadolinium oxide o loʻo i ai mea sili ona lelei ma faʻamaneta. O loʻo i ai se faʻamaufaʻailoga maualuga ma le faʻaogaina o le malamalama lelei i totonu o le vaʻaia o le malamalama, lea e faʻavaeina ai le faʻavae mo lona faʻaogaina i totonu o le fanua opitika. I le taimi lava e tasi, o le 4f electron shell structure o le gadolinium ion e tuʻuina atu ia te ia mea faʻapitoa faʻamaneta.

2. Vaega autu fa'aoga ole gadolinium oxide
I totonu o le falemaʻi, o le faʻaaogaina sili ona taua o le gadolinium oxide o se mea mataʻutia mo faʻataʻitaʻiga faʻamaneta (MRI) faʻatusatusaga. Gadolinium complexes e mafai ona matua suia le taimi malolo o vai protons, faʻaleleia le faʻatusatusaina o ata, ma maua ai ata manino mo faʻamaʻi faʻamaʻi. O lenei talosaga ua matua faʻalauiloaina le atinaʻeina o tekinolosi faʻafomaʻi faʻaonaponei.
I le fanua o mea maneta, gadolinium oxide o se mea autu autu mo le saunia o mea maneta e pei o le gadolinium iron garnet (GdIG). O nei meafaitino e taua tele i masini microwave ma masini magneto-optical, ma tuʻuina atu se faʻavae mea mo le atinaʻeina o tekinolosi fesoʻotaʻiga faʻaonaponei.
I faʻaoga faʻapitoa, o le gadolinium oxide e faʻaaogaina lautele i phosphors, mea laser, faʻapipiʻi faʻapipiʻi ma isi fanua ona o ana mea faʻapitoa lelei. Aemaise lava i le sauniuniga o ata tifaga mataʻutia-faʻasinomaga, gadolinium oxide o loʻo faʻaalia tulaga lelei.
I tekinolosi faaniukilia malosi, gadolinium oxide o loʻo faʻaaogaina e avea o se mea e faʻatonutonu ai le tootoo mo reactors faaniukilia ona o le maualuga o le neutron absorption cross section. O lenei talosaga e taua tele i le saogalemu o le faagaoioiga o reactors faaniukilia.
3. Atina'e i le lumana'i o le gadolinium oxide
Faatasi ai ma le alualu i luma o tekinolosi sauniuni, o le auala faʻapipiʻi o le gadolinium oxide ua faʻaauau pea ona faʻaleleia. Mai le faiga fa'asolo-vaega fa'aleaganu'u tu'ufa'atasiga i le auala fa'asolosolo sol-gel, o le fa'aleleia atili o le fa'agasologa o sauniuniga ua fa'aleleia atili ai le mama ma le fa'atinoga o le gadolinium oxide.
I fanua faʻaoga faʻapitoa, o le gadolinium oxide o loʻo faʻaalia ai le malosi tele. I faʻamalama faʻamalama, faʻasologa faʻatusatusa, pulega o le siosiomaga ma isi vaega, o loʻo suʻesuʻeina e le au suʻesuʻe ni faʻaoga fou o le gadolinium oxide. O nei suʻesuʻega ua tatalaina ai faʻamatalaga fou mo le atinaʻeina o le gadolinium oxide i le lumanaʻi.
Mai le vaʻaiga o faʻamoemoega o alamanuia, faʻatasi ai ma le faʻavaveina o le atinaʻeina o fuafuaga faʻalauiloa faʻapitoa e pei o le malosi fou ma mea fou, o le a faʻaauau pea ona tupu le manaʻoga maketi mo le gadolinium oxide. Aemaise lava i fanua o gaosiga maualuga ma tekinolosi faʻatekonolosi, o le taua o le gadolinium oxide o le a faʻaleleia atili.
I le avea ai o se sui taua o le aiga e le masani ai le lalolagi, o le taua o le gadolinium oxide e le gata o loʻo atagia i le tele o faʻaoga o loʻo iai nei, ae faʻapea foʻi i ona avanoa e le gata i le atinaʻeina o tekonolosi i le lumanaʻi. Mai le soifua maloloina faʻafomaʻi i le tekonolosi malosi, mai faʻamatalaga fesoʻotaʻiga i le puipuiga o le siosiomaga, o le gadolinium oxide o loʻo faia ni sao taua i le alualu i luma o le saienisi ma tekinolosi a le tagata ma ona uiga tulaga ese. Faatasi ai ma le faʻaauauina o le atinaʻeina o mea faʻasaienisi, gadolinium oxide o le a mautinoa lava le susulu i le tele o fanua ma faʻaauauina le mataupu lauiloa o mea e le masani ai le lalolagi.
