Hakar, shiri da amintaccen ajiya naGadolinium Oxide (GD₂o₃)muhimman bangarori ne na rare duniya aiki. Mai zuwa cikakken bayani ne:
一, hanyar hakar gadaoliniaum oxide
Yawancin gonolinium yawanci ana fitar da shi ne daga m jihar Ors da ke dauke da Gadolinium, ores sun haɗa da Menezite da Basnäsite. Tsarin hakar ya hada da matakan masu zuwa:
1.ore bazuwar:
Racalasa duniya mai wuya ana bazu ta hanyar acid ko alkalanta.
Hanyar acid: bi da nor da mai da hankali sulfuric acid ko hydrochloric acid don maye gurbin abubuwan duniya da yawa cikin ƙyalli.
Hanyar Alkaline: Yi amfani da sodium hydroxide ko potassium hydroxide ko potassium hydroxide ko potassium hydroxide ko potassium hydroxide ko potassium hydroxide ko potassium hydroxide.
2.rare duniya rabuwa:
Raba gadolinium daga hadewar maganganu mai wuya ta hanyar haifar da hakar ko musayar ion.
Hanyar hakar za ta warware: Yi amfani da abubuwan haɗin gwiwar kwayoyin cuta (kamar trivutyl phosphate) don selectived cirewa gadolinium ions.
Hanyar musaya: Yi amfani da ion musayar don raba gadolinium.
3.purification na gadolinium:
Ta hanyar karin abubuwa ko musayar ƙasa, sauran karancin duniya da impurities an cire su don samun daskararren Gadolinium ko kuma gadolinium nitrate).
4.
Gadolinium wanda aka tsarkake (kamar gandaum nitrate ko gaddolinium okalate) ana calcin zazzabi a babban zazzabi don yanke jiki da samar da gaddoliniaum oxide.
Alamar dauki: 2 GD (Babu₃) ₃ → GD₂o₃ + 6 No₂ + 3/2 o₂
, Shiri Hanyar gadolinium oside
1.highight zazzabi Lissafin Lissafi:
Calcine Salts Salts (kamar gadolinium nitrate, gadolinium carbleate) a babban zazzabi (sama da 800 ° C) don lalata da kuma samar da gadoliniaum oxide.
Wannan shine mafi yawan hanyar shiri da aka saba amfani da shi kuma ya dace da manyan-sikelin samarwa.
2. Shahararren Hanyar Hanyar:
Gadolinium Oxide nanoparticles ana samarwa ta hanyar amsawa na gadolinium da alkaline mafita a karkashin babban zazzabi da kuma m hydrothermal yanayin.
Wannan hanyar na iya shirya babban gunkiyar gayanci na oxide tare da girman barbashi.
3.Sana-gel-gel:
Gadolinium salts ne gauraye da abubuwan da ke ciki na kwayoyin halitta (kamar citric acid) don samar da Sol, wanda aka buga, bushewa da clored don samun giloliniaum oxide.
Wannan hanyar ta dace da shirya Nano-sikelin gurnolinium oxide foda.
, Yanayin ajiya mai aminci na gadoliniaum oxide
Gadolinium Oxide yana da tushe a dakin da zazzabi, amma har yanzu ana lura da yanayin ajiya mai zuwa don tabbatar da aminci da aikin kayan aiki:
1.Moerure-undu:
Gadolinium Oxide yana da takamaiman mataki na hygroscopicity kuma ya kamata a adana shi a cikin yanayin bushewa don kauce wa hulɗa da danshi.
An bada shawara don amfani da wani akwati da aka rufe kuma ƙara willicant (kamar silica gel).
Sallah :::
Gadolinium Oxide yana kula da haske, da kuma fuskantar dogon lokaci haske zai iya shafar aikinsa.
Ya kamata a adana shi a cikin sanyi, duhu.
3.Tempeates iko:
Ya kamata a sarrafa zazzabi a cikin kewayon zazzabi ɗakin (15-25 ° C), guje wa mahalli mai yawa ko ƙananan yanayin yanayi.
Babban zazzabi na iya haifar da canje-canje na tsarin tsari a gadoliniaum oxide, da ƙarancin zafin jiki na iya haifar da hygrostcopicity.
4. A.
Gadolinium Oxide shine alkaline oxide kuma zai yi amsawa da karfi tare da acid.
Kiyaye daga abubuwa na acidic a lokacin ajiya.
5.Prenvent ƙura:
Gadolinium Oxide foda na iya bushewa dajin numfashi da fata.
Yi amfani da kwantena da aka rufe yayin adanawa da kuma sanya kayan kariya (kamar su hannu) lokacin da ake kulawa.
IV. Matakan kariya
1.Toxicity:Gadolinium Oxide da kanta yana raguwa cikin guba, amma ƙurar ta na iya tsoratar da hanjin numfashi da fata, don haka ya kamata a guji kai tsaye.
2.Wase zubar da kai:Sharar abu gadolinium oxide ko a bi da shi daidai da ka'idojin mikawa da ke haɗarin da zai guji gurbata muhalli.
Ta hanyar hakar da ke sama, shiri da hanyoyin ajiya, ingantacciyar hanyar gadolinia za a iya samu sosai kuma a amince haɗuwa da bukatun sa a cikin filayen kayan magnetic, kayan aiki, da sauransu.
