Soo saarista, diyaarinta iyo kaydinta nabdoon eegadolinium oxide (Gd₂O₃)waa dhinacyo muhiim u ah farsamaynta curiyaha dhulka naadir. Kuwa soo socda waa sharraxaad faahfaahsan:
一, Habka soo saarista ee oxide gadolinium
Gadolinium oxide waxaa inta badan laga soo saaraa macdanta dhulka naadirka ah oo ay ku jiraan gadolinium, macdanta caadiga ah waxaa ka mid ah monazite iyo bastnäsite. Habka soo saarista inta badan waxa ku jira talaabooyinka soo socda:
1.Ore qurmay:
Macdanta dhulka naadirka ah waxa ay ku qudhuntaa aashitada ama habka alkaline.
Habka aysiidhka: Ku daawee macdanta sulfuric acid ama hydrochloric acid si aad ugu beddesho walxaha dhifka ah ee dhulka milix dhalada.
Habka alkaline: Isticmaal sodium hydroxide ama potassium hydroxide si aad u dhalaaliso macdanta heerkulka sare si aad ugu beddesho curiyeyaasha dhulka dhifka ah hydroxide.
2. Dhulka naadirka ah:
Kala sooc gadolinium oo ka sooca xalalka dhulka dhifka ah ee isku qasan iyadoo la soo saarayo dareeraha ama ion beddelka.
Habka soo saarista dareeraha: Isticmaal dareerayaasha organic (sida tributyl phosphate) si aad si xushmad leh u soo saartid ion gadolinium.
Habka sarrifka Ion: Isticmaal xabagta beddelka ion si aad u kala soocdo ion gadolinium.
3.Nadiifinta gadolinium:
Iyada oo loo marayo soo saaris badan ama isweydaarsiga ion, walxaha kale ee dhifka ah ee dhulka iyo wasakhda ayaa laga saaraa si loo helo xeryahooda gadolinium-ka saafiga ah (sida gadolinium chloride ama gadolinium nitrate).
4. U beddelashada gadolinium oxide:
Dhismaha gadolinium-ka la safeeyey (sida gadolinium nitrate ama gadolinium oxalate) ayaa lagu xisaabiyaa heerkul sare si uu u burburiyo oo uu u dhaliyo oxide gadolinium.
Tusaalaha falcelinta: 2 Gd(NO₃)₃ → Gd₂O₃ + 6 NO₂ + 3/2 O₂
二, Habka diyaarinta ee oxide gadolinium
1. Habka calcination heerkulka sare:
Calcine gadolinium cusbada (sida gadolinium nitrate, gadolinium oxalate ama gadolinium carbonate) heerkulka sare (ka sarreeya 800 ° C) si ay u jajabiso oo ay u abuurto oxide gadolinium.
Tani waa habka diyaarinta ee inta badan la isticmaalo waxayna ku habboon tahay wax soo saarka ballaaran.
2. Habka Heerkulbeegga:
Gadolinium oxide nanoparticles waxaa soo saara falcelinta cusbada gadolinium oo leh xalalka alkaline ee hoos yimaada heerkulka sare iyo xaaladaha heerkulka sare ee cadaadiska.
Habkani wuxuu diyaarin karaa gadolinium oxide nadiif ah oo nadiif ah oo leh cabbirka walxaha isku midka ah.
3. Habka Sol-gel:
Cusbada Gadolinium waxaa lagu daraa horudhacyaal dabiici ah (sida citric acid) si ay u sameeyaan sol, kaas oo markaa la shiilay, la qalajiyey oo la kariyey si loo helo oxide gadolinium.
Habkani wuxuu ku habboon yahay diyaarinta nano-scale gadolinium oxide budada.
三, Xaaladaha kaydinta nabdoon ee gadlinium oxide
Gadolinium oxide waa mid deggan heerkulka qolka, laakiin xaaladaha kaydinta soo socda waa in weli la xuso si loo hubiyo badbaadada iyo waxqabadka alaabta:
1.Qoyaan-celiya:
Gadolinium oxide waxay leedahay heer gaar ah oo hygroscopicity ah waana in lagu kaydiyaa jawi qallalan si looga fogaado taabashada qoyaanka.
Waxaa lagu talinayaa in la isticmaalo weel xiran oo lagu daro qalajiyaha (sida jelka silica).
2.Ilays-caddeyn:
Gadolinium oxide waxay u nugul tahay iftiinka, soo-gaadhista muddada-dheer ee iftiinka xooggan waxay saameyn kartaa waxqabadkeeda.
Waa in lagu kaydiyaa meel qabow oo mugdi ah.
3. Xakamaynta heerkulka:
Heerkulka kaydinta waa in lagu xakameeyaa inta u dhaxaysa heerkulka qolka (15-25 ° C), iyada oo laga fogaanayo jawi heerkulkiisu sarreeyo ama hooseeya.
Heerkulka sare wuxuu keeni karaa isbeddel qaabdhismeed oxide gadolinium, iyo heerkulka hooseeya wuxuu keeni karaa hygroscopicity.
4.iska ilaali xidhiidhka aashitada:
Gadolinium oxide waa oksaydh alkaline wuxuuna si ba'an uga falcelinayaa aashitada.
Ka fogow walxaha acidic ah inta lagu jiro kaydinta.
5.Ka hortag boodhka:
Budada Gadolinium oxide waxay ka xanaajin kartaa mareenka neefsiga iyo maqaarka.
Isticmaal weelasha xidhan marka aad kaydinayso oo xidho qalabka ilaalinta (sida maaskaro iyo galoofyada) marka aad gacanta ku hayso.
IV. Ka taxadaritaan
1. Sunta:Gadolinium oxide lafteedu way ku yar tahay sunta, laakiin boodhkeeda ayaa laga yaabaa inay ka xanaajiso mareenka neefsiga iyo maqaarka, markaa waa in la iska ilaaliyaa xidhiidhka tooska ah.
2.Qashinka daadinta:Qashinka gadolinium oxide waa in dib loo warshadeeyay ama lagu daaweeyaa si waafaqsan xeerarka xakamaynta kiimikooyinka khatarta ah si looga fogaado wasakhowga deegaanka.
Iyadoo loo marayo soo saarista kor ku xusan, diyaarinta iyo hababka kaydinta, gadolinium oxide oo tayo sare leh ayaa lagu heli karaa si hufan oo ammaan ah si loo daboolo baahideeda dhinacyada qalabka magnetic, qalabka indhaha, sawirka caafimaadka, iwm.
