Ibhekiswe njani kwaye ilungiselelwe njani kwaye ilungiselelwe? Zithini iimeko zokugcina ngokukhuselekileyo?

Ukukhutshwa, ukulungiselela kunye nokugcinwa okukhuselekileyoIGadolinium Oxide (GD₂O₃)zizinto ezibalulekileyo zokulungiswa komhlaba onqabileyo. Oku kulandelayo yinkcazo eneenkcukacha:

 

一, indlela yokukhupha i-gadoliium oxide

 

I-Gadolinium Oxide idla ngokukhutshwa kwi-ores enqabileyo ye-gedolinium, iores eqhelekileyo iquka i-monazite kunye ne-bastnäsite. Inkqubo yokukhuphela ibandakanya amanyathelo alandelayo:

 

1.OreAre

 

Umhlaba onqabileyo we-ore ugqityiwe yi-acid okanye indlela ye-alkaline.

 

Indlela ye-acid: phatha i-ore nge-sulfuric acid okanye i-hydrochloric acid ukuguqula izinto ezinqabileyo zomhlaba zibe ziityiwa.

 

Indlela ye-alkaline: sebenzisa i-sodium hydroxide okanye potassium hydroxide ukuze unyibilike kwiqondo lokushisa eliphezulu ukuguqula izinto ezinqabileyo zomhlaba kwi-hydroxides.

 

2.Fumi:

 

Yahlula i-gadolinium evela kwizisombululo zomhlaba ezixutywe ngumhlaba ngeSolvent okanye i-ion yotshintshiselwano.

 

Indlela yokukhupha i-Solvent: Sebenzisa izinyibilikisi zezinto eziphilayo

 

Indlela yotshintshiselwano

 

3.Ukuhlala kweGadilinium:

 

Through multiple extractions or ion exchange, other rare earth elements and impurities are removed to obtain high-purity gadolinium compounds (such as gadolinium chloride or gadolinium nitrate).

 

4.Khuseleko kwiGadolinium Oxide:

 

I-Gadoliium ehlanjululwe (njenge-Gadolinium ye-Gadolinium okanye i-Gadolinium Oxsalalate) i-Isced kwiqondo lokushisa eliphezulu ukuvelisa kwaye livelise i-gadolinium oxide.

 

Umzekelo wokuphendula: 2 GD (Hayi) ₃ ₃ → I-GDTO₃ + 6 Hayi₂ + 3/2 o₂

I-Gadolinium oxide yokukhupha i-gadchan

, Indlela yokulungiselela yeGadoliium oxide

 

I-1.High yendlela yokuCoca indlela:

 

Calciene Gadolinium ze-Gadolinium (njenge-Gadolinium nitrate, i-gadolinium oxilate) okanye i-Gadolinium Carbonate) ukubola kwaye kuvelise i-gadolnium oxide.

 

Le yeyona ndlela isetyenziswayo yokulungiselela kwaye ilungele imveliso enkulu.

 

I-2.Shydrothel Kialm:

 

I-gadollinium oxial axicles iveliswa ngokuphendula i-Gadolinium ye-GADOLINIA ye-alkaline solutions phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu lweemeko ze-hydrothermal.

 

Le ndlela inokulungiselela i-gedolinium ephezulu ye-geadolium enobungakanani be-interm.

 

I-3.lsol-gel ye-gel:

 

I-Gadolinium ixutywe ne-orcurster (enje nge-cicric acid) ukwenza i-SOL, emva koko ivuthayo, eyomileyo neyifumana i-gadolnium oxide.

 

Le ndlela ilungele ukulungiselela i-Nano-cack Gadolium Oxide Powder.

三, iimeko zokugcina ezikhuselekileyo zeGadolinium Oxide

 

I-Gadolinium Oxide isizinza kubushushu begumbi, kodwa ezi meko zokugcina zilandelayo kufuneka ziqwalaselwe ukuqinisekisa ukhuseleko kunye nokusebenza kwezinto:

 

1.morinta-ubungqina:

 

I-gadolinium oxide inenqanaba elithile le-hygroscoficity kwaye kufuneka igcinwe kwindawo eyomileyo ukuthintela ukunxibelelana nomswakama.

 

Kucetyiswa ukuba usebenzise isikhongozeli esitywiniweyo kwaye wongeze i-deccoccant (njenge-silica gel).

 

2. Ubungqina-:

 

I-gadolinium oxide inovelwano kukukhanya, kunye nokuvezwa kwexesha elide ukukhanya kunokuchaphazela ukusebenza kwalo.

 

Kufuneka igcinwe kwindawo epholileyo, emnyama.

 

Ulawulo lwe-3.ultetrocape:

 

Amaqondo obushushu agciniweyo kufuneka alawulwe ngaphakathi kuluhlu lobushushu begumbi (15-25 ° C), ukunqanda iindawo eziphezulu zobushushu okanye eziphantsi.

 

Amaqondo obushushu aphezulu anokubangela utshintsho lwesakhiwo kwi-gadolinium oxide, kwaye amaqondo obushushu asezantsi anokubangela i-hygroscoficity.

 

Unxibelelwano lwe-Acid:

 

I-gadolinium oxide yi-alkaline oxide kwaye iya kuphendula nge-acid.

 

Hlala kude nezinto ze-acidic ngexesha lokugcina.

 

5. Uthuli lothuli:

 

I-Gadolinium Oxider Proder inokucaphukisa iphecana lokuphefumla kunye nolusu.

 

Sebenzisa izikhongozeli ezitywiniweyo xa ugcina kwaye unxibe izixhobo zokhuselo (njengemaski kunye neegloves) xa uphatha.

 

Iv. Ukulumkela

 

I-1.toty:I-Gadolinium iphantsi iphantsi kwetyhefu, kodwa uthuli lwayo lusenokucaphukisa iphecana kunye nolusu, ngoko uqhakamshelwano ngqo kufuneka luthintelwe.

 

I-2waste yalapho:Inkunkuma uGadolinium oxide kufuneka iphinde isebenze okanye inyangwe ngokungqinelana ne-Ismazard Coving Plazas Comment imigaqo yokuphepha ungcoliseko lwendalo.

 

Ngolwazi lokukhutshelwa apha ngasentla, ukulungiselela kunye neendlela zokugcina, i-gedolim ephezulu ye-Gadolinium inokufumaneka ngokukuko nangokukhuselekileyo ukuze ihlangane iimfuno zemagnethi, izixhobo ze-optical, ingcinga yonyango, njl njl.

IXESHA LOKUQALA: FEB-28 ukuya ku-525
