Kuongororwa, kugadzirira uye kuchengetedza kwakachengeteka kweGadolinium Oxide (GD₂O₃)Izvo zvakakosha zvikamu zveKashoma pasi element element kugadzirisa. Izvi zvinotevera kutsanangurwa kwakadzama:
一, nzira yekubvisa yeGadolinium oxide
Gadolinium oxide inowanzo kubviswa kubva pane zvisingawanzo kuitika pasi paGadolinium, zvakajairika Ores inosanganisira Monazi uye Bastnänsite. Maitiro ekubvisa anonyanya kusanganisira matanho anotevera:
1.ore kuora:
Iyo nguva isingawanzo ore yakaderedzwa neAcid kana alkaline nzira.
Acid Nzira: Bata iyo ore neiyo yakamisikidzwa sulfutic acid kana hydrochloric acid kushandura iyo isingawanzo nyika zvinhu zvine saluble munyu.
Nzira yeAlkaline: Shandisa Sodium Hydroxide kana Potassium Hydroxide kuti inyunguduke iyo ore tembiricha yekushandura tembiricha kushandura zvinhu zvisingawanzo kuita hydroxides.
2.rare Pasi Kuparadzanisa:
Kuparadzanisa Gadolinium kubva kusanganisa zvisingaverengeki pasi pasi mhinduro ne solvent kuronga kana ion kuchinjana.
Solvent Ortsction nzira: Shandisa organic sol solvent (senge tributyl phosphate) kusarudza kuendesa Gadolinium Ions.
Ion eSechange nzira: Shandisa Ion exchange resin kupatsanura Gadolinium Ions.
3.Pugsification yeGadolinium:
Kuburikidza nekuwedzera kwakawanda kana Ion kuchinjanisa
4.conversion kune gadolinium oxide:
Iyo yeGadolinium compound (senge gadolinium nitrate kana gadolinium oxacalate) inokandirwa tembiricha yakakwira kuti igadzirise uye gadzira Gadolinium oxide.
Reaction Saterion: 2 GD (no₃) ₃ → GD₂O₃ + 6 No₂ + 3/2 o
二, nzira yekugadzirira yeGadolinium oxide
1.high tembiricha calcination nzira:
Calcine Gadolinium Salts (yakadai seGadolinium Nitrate, Gadolinium Carbonate) Pakushongedza Kwakanyanya (pamusoro 800 ° C) kuti gadzira uye gadzira Gadolinium Oxide.
Iyi ndiyo nzira inowanzoitwa yekugadzirira inogadzirira uye yakakodzera kugadzirwa kukuru-kugadzirwa.
2.hydrothermal nzira:
Gadolinium oxide inogadzirwa nekuita Gadolinium Salts neAlkaline Solutions pasi pekushisa kwakanyanya uye yakakwirira kudzvinyirira hydrothermal mamiriro.
Iyi nzira inogona kugadzirira yakakwirira-iyo Pollity Gadolinium oxide neunifomu size.
3.Sefa-gel nzira:
Gadolinium Salts akasanganiswa ne organic precurs (akadai secitric acid) kuumba sol, iyo yakabva yaoma, yakaoma uye yakaomeswa kuwana gadolinium oxide.
Iyi nzira yakakodzera kugadzirira nano-chiyero gadolinium oxder poda.
三, mamiriro akachengeteka ekuchengetedza eGadolinium oxide
Gadolinium oxide yakamanikidzwa pamhepo tembiricha, asi iyo inotevera mamiriro ekuchengetedza inofanira kucherechedzwa kuti ive nechokwadi chekuchengetedza uye kuita zvinhu:
1.merure-chiratidzo:
Gadolinium oxide ine imwe nhanho yehyotroscopicity uye inofanira kuchengetwa munzvimbo yakaoma yekudzivirira kusangana nemunyoro.
Zvinokurudzirwa kushandisa mudziyo wakasungwa uye wedzera didicant (senge silica gel).
2.Light-Proof:
Gadolinium oxide inonzwa nehanya nechiedza, uye kuratidzwa kwenguva refu kune mwenje wakasimba kunogona kukanganisa maitiro ayo.
Inofanira kuchengetwa munzvimbo inotonhorera, ine rima.
3.Temperature control:
Iyo tembiricha yekuchengetedza inofanirwa kudzorwa mukati mehukuru hwemakamuri tembiricha (15-25 ° C), kudzivirira yakakwirira kana yakaderera tembiricha.
Tembiricha yakakwira inogona kukonzera shanduko yemhando muGadolinium oxide, uye tembiricha yakaderera inogona kukonzera hygroscopicpicity.
4.ROVOD kusangana naAsid:
Gadolinium oxide in a alkaline oxide uye ichaita nechisimba neakadhidhi.
Ramba usiri kure nezvinhu zvemukati panguva yekuchengetedza.
5.PREVENGENTER GROU:
Gadolinium oxide poda inogona kutsamwisa turakiti rekufema uye ganda.
Shandisa midziyo yakasungwa kana ichichengetedza uye kupfeka michina yekudzivirira (senge masks uye magurovhosi) paunenge uchibata.
Iv. Zvekungwaririra
1.Kunongedzwa:Gadolinium Ocedice pachayo kuti akaderera mukupfuya, asi guruva rayo rinogona kutsamwisa turakiti rekufema uye ganda, saka kubatana kunofanirwa kudzivirirwa.
2.waste disposal:Tsvina Gadolinium oxide inofanira kugadzirwazve kana kurapwa zvinoenderana nemakemikari ane ngozi kubata mitemo kuti arege kusvibiswa kwezvakatipoteredza.
Kuburikidza neyekupedzisira pamusoro
