YINTONI UKUSETYENZISWA KWE-GADOLINUM OXIDE?

I-Gadolinium oxide, ekwaziwa ngokuba yi-gadolinia, yikhompawundi yeekhemikhali eyinxalenye yodidi lweeoksidi zomhlaba ezinqabileyo. Inombolo ye-CAS ye-gadolinium oxide yi-12064-62-9. Ingumgubo omhlophe okanye ophuzi onganyibilikiyo emanzini kwaye uzinzile phantsi kweemeko eziqhelekileyo zokusingqongileyo. Eli nqaku lixubusha ukusetyenziswa kwe-gadolinium oxide kunye nokusetyenziswa kwayo kwiinkalo ezahlukeneyo.

1. IMagnetic Resonance imaging (MRI)

I-Gadolinium oxideisetyenziswa ngokubanzi njenge-agent echaseneyo kwi-imaging magnetic resonance imaging (MRI) ngenxa yeempawu zayo ezizodwa zemagneti. I-MRI sisixhobo sokuxilonga esisebenzisa i-magnetic field eyomeleleyo kunye namaza erediyo ukwenza imifanekiso yamalungu angaphakathi kunye nezicubu zomzimba womntu. I-Gadolinium oxide inceda ukuphucula ukungafani kwemifanekiso ye-MRI kwaye yenza kube lula ukwahlula phakathi kwezicubu ezinempilo kunye nezigulayo. Isetyenziselwa ukufumanisa iimeko ezahlukeneyo zonyango ezinje ngamathumba, ukudumba, kunye namahlule egazi.

2. IiReactor zeNyukliya

I-Gadolinium oxideikwasetyenziswa njengento yokufunxa inyutroni kwizixhobo zenyukliya. I-Neutron absorbers zizinto ezisetyenziselwa ukulawula izinga leentshukumo zokuqhekeka kwenyukliya ngokucotha okanye ukufunxa iinyutroni ezikhutshwe ngexesha lokusabela. I-Gadolinium oxide inomnqamlezo we-nutroni yokufunxa ephezulu, eyenza ibe sisixhobo esisebenzayo sokulawula ukusabela kwetsheyini kwizixhobo zenyutroni. Isetyenziswa kuzo zombini ii-pressurized water reactors (PWRs) nakwi-boiling water reactors (BWRs) njengenyathelo lokhuseleko lokuthintela iingozi zenyukliya.

3. I-Catalysis

I-Gadolinium oxideisetyenziswa njenge catalyst kwiinkqubo ezahlukeneyo zoshishino. I-Catalysts zizinto ezonyusa izinga lokusabela kweekhemikhali ngaphandle kokutyiwa kwinkqubo. I-Gadolinium oxide isetyenziswa njenge-catalyst kwimveliso ye-methanol, i-ammonia, kunye nezinye iikhemikhali. Ikwasetyenziselwa ukuguqulwa kwekhabhon monoxide kwicarbon dioxide kwiinkqubo zokukhupha iimoto.

4. I-Electronics kunye ne-Optics

I-Gadolinium oxide isetyenziselwa ukuveliswa kwezinto zombane kunye nezixhobo ezibonakalayo. Isetyenziswa njenge-dopant kwii-semiconductors ukuphucula ukuhanjiswa kombane kunye nokudala izixhobo zombane ze-p. I-Gadolinium oxide iphinda isetyenziswe njengephosphor kwi-cathode ray tubes (CRTs) kunye nezinye izixhobo zokubonisa. Ikhupha ukukhanya okuluhlaza xa ivuselelwe ngumqa we-electron kwaye isetyenziselwa ukudala umbala oluhlaza kwiiCRT.

5. Ukwenziwa kweglasi

I-Gadolinium oxideisetyenziswa kwimveliso yeglasi ukuphucula ukungafihli kunye nesalathiso sokugqabhuka seglasi. Yongezwa kwiglasi ukwandisa ubuninzi bayo kunye nokukhusela umbala ongafunekiyo. IGadolinium oxide ikwasetyenziswa ekuveliseni iglasi ekumgangatho ophezulu yeelensi kunye neeprism.

Ukuqukumbela

Ukuququmbela,i-gadolinium oxideinoluhlu olubanzi lwezicelo kwiindawo ezahlukeneyo. Iimpawu zayo ezikhethekileyo zemagneti, i-catalytic, kunye ne-optical ziyenza ibe yimathiriyeli exabisekileyo ukuze isetyenziswe kunyango, kwimizi-mveliso nakwinzululwazi. Ukusetyenziswa kwayo kuye kwabaluleka kakhulu kwiminyaka yakutshanje, ngakumbi kwicandelo lezonyango, apho isetyenziswa njenge-agent echaseneyo kwi-MRI scans. Ukuguquguquka kwe-gadolinium oxide kuyenza ibe yimathiriyeli ebalulekileyo kuphuculo lwetekhnoloji eyahlukeneyo kunye nokusetyenziswa.
