Walaxda budada cad ma aha oo kaliya xubin muhiim ah oo ka mid ah oksaydhyada dhulka naadirka ah, laakiin sidoo kale waa qalab lagama maarmaanka u ah horumarinta sayniska iyo farsamada casriga ah. Laga soo bilaabo sawir-qaadista caafimaadka ilaa tignoolajiyada tamarta nukliyeerka, laga bilaabo qalabka magnetic ilaa aaladaha indhaha, gadolinium oxide waa meel walba, taasoo muujineysa qiimaha gaarka ah ee walxaha dhifka ah ee dhulka.
1. Astaamaha aasaasiga ah ee oxide gadolinium
Gadolinium oxidewaa oksaydh dhulka naadirka ah ee caadiga ah oo leh qaab-dhismeedka crystal cubic. Qaab dhismeedkeeda crystal, ion gadolinium iyo ion ogsijiin ayaa lagu daraa habayn meel gaar ah si loo sameeyo curaarta kiimikaad deggan. Qaab dhismeedkani wuxuu siinayaa gadolinium oxide barta dhalaalaysa ilaa 2350 ° C, taas oo u oggolaanaysa inay ku xasilloonaato jawiga heerkulka sare.
Marka la eego sifooyinka kiimikada, oxide gadolinium wuxuu muujiyaa sifooyinka caadiga ah ee oksaydhka alkaline. Waxay la falgali kartaa asiidh si ay u samayso milix u dhigma waxayna leedahay hygroscopicity gaar ah. Tilmaamahani waxay u baahan yihiin kaydin gaar ah iyo xaaladaha maaraynta gadolinium oxide inta lagu jiro diyaarinta walxaha.
Marka la eego sifooyinka jireed, oxide gadolinium wuxuu leeyahay sifooyin muuqaal iyo magnetic aad u fiican. Waxay leedahay index refractive sare iyo gudbinta iftiinka wanaagsan ee gobolka iftiinka muuqda, kaas oo dhigaya aasaaska codsigeeda ee goobta indhaha. Isla mar ahaantaana, qaab dhismeedka qolofka elektaroonigga ah ee 4f ee gadolinium ion wuxuu siinayaa sifooyin magnetic u gaar ah.

2. Aagagga codsiga asaasiga ah ee gadolinium oxide
Dhinaca caafimaadka, codsiga ugu muhiimsan ee gadolinium oxide waa sida alaabta ceeriin ee sawir-qaadista magnetic resonance imaging (MRI). Dhismayaasha Gadolinium waxay si weyn u beddeli karaan wakhtiga nasashada ee protons-ka biyaha, waxay hagaajin karaan isbarbardhigga sawirka, waxayna bixiyaan sawirro cad oo lagu ogaanayo cudurka. Codsigan ayaa si weyn kor ugu qaaday horumarinta tignoolajiyada sawir-qaadista caafimaadka ee casriga ah.
Marka la eego qalabka magnetic, gadolinium oxide waa alaabta ceeriin ee muhiimka ah ee loogu talagalay diyaarinta alaabta magnetic sida gadolinium iron garnet (GdIG). Qalabkani waxa ay door muhiim ah ka ciyaaraan aaladaha microwave-ka iyo aaladaha magneto-optical-ka, waxayna bixiyaan saldhig maaddada horumarinta tignoolajiyada isgaarsiinta casriga ah.
Codsiyada indhaha, oxide gadolinium waxaa si weyn loogu isticmaalaa fosfooraska, qalabka laysarka, dahaarka indhaha iyo meelaha kale sababtoo ah sifooyinka muuqaalka ugu fiican. Gaar ahaan diyaarinta filimaanta indhaha ee sare-soo-celinta-index, gadolinium oxide waxay muujinaysaa faa'iidooyin gaar ah.
Tiknoolajiyada tamarta nukliyeerka, oxide gadolinium waxaa loo isticmaalaa sidii shayga xakamaynta ee reactors nukliyeerka sababtoo ah qaybta nuugista neutron-ka sare. Codsigan ayaa muhiimad weyn u leh hawlgalka badbaadada leh ee reactors nukliyeerka.
3. Horumarinta mustaqbalka ee oxide gadolinium
Horumarinta tignoolajiyada diyaarinta, habka isku-dhafka ah ee gadolinium oxide ayaa si joogto ah loo hagaajiyay. Laga soo bilaabo habka falcelinta adag ee dhaqameed ee habka hore ee sol-gel, hagaajinta habka diyaarinta ayaa si weyn u wanaajisay nadiifinta iyo waxqabadka gadolinium oxide.
Goobaha codsiyada soo baxaya, gadolinium oxide waxay muujinaysaa karti weyn. Nalalka adag ee dawlad-goboleedka, xisaabinta quantum-ka, maamulka deegaanka iyo dhinacyo kale, cilmi-baarayaashu waxay sahamiyaan codsiyada cusub ee oxide gadolinium. Sahankan ayaa furay jihooyin cusub oo loogu talagalay horumarinta mustaqbalka ee oxide gadolinium.
