Los ntawm kev kho mob ua rau nuclear lub zog tshuab, los ntawm cov khoom sib nqus rau cov khoom siv kho kom zoo nkauj, gadolinium oxide yog qhov chaw tshwj xeeb ntawm cov khoom lag luam tsis tshua muaj txiaj ntsig.
1. Cov khoom yooj yim ntawm Gadolinium oxide
Gadolinium oxideyog ib lub ntiaj teb tsawg tsawg oxide nrog lub cubic crystal qauv. Hauv nws cov qauv siv lead ua, gadolinium ions thiab cov pa ions tau sib xyaw ua ke rau cov kev sib raug zoo ntawm kev ruaj khov. Cov qauv no muab cov gadolinium oxide cov roj melting txog li 2350 ° C, tso cai rau nws nyob ruaj khov nyob rau hauv ib puag ncig kub siab.
Nyob rau hauv cov nqe lus ntawm cov tshuaj lom neeg, gadolinium oxide cov tshuaj ntsuam ib txwm alkide cov yam ntxwv. Nws tuaj yeem hnov cov kua qaub los ua cov ntsev ua kom zoo thiab muaj qee yam kev hygroscopicity. Cov yam ntxwv no yuav tsum muaj kev cia khoom tshwj xeeb thiab tuav cov kev mob rau Gadolinium oxide thaum npaj khoom.
Hais txog cov khoom siv lub cev, gadolinium oxide muaj cov khoom siv kho tshiab zoo thiab sib nqus. Nws muaj lub siab ua haujlwm siab thiab qhov pom kev zoo nyob hauv thaj av pom pom, uas ua rau lub hauv paus rau nws daim ntawv thov hauv qhov muag. Nyob rau tib lub sijhawm, 4F Electron plhaub qauv ntawm Gadolinium Ions muab nws cov cim sib nqus.

2. Daim ntawv thov tseem ceeb ntawm Gadolinium oxide
Hauv kev kho tsev kho mob, cov ntawv thov tseem ceeb tshaj plaws ntawm gadolinium oxide yog cov khoom siv raw rau kev ua kom sib luag (MRI) cov neeg sawv cev sib txawv. Gadolinium cov complexes tuaj yeem hloov lub sijhawm so ntawm cov protons dej, txhim kho cov duab sib piv rau kev kuaj mob. Daim ntawv thov no tau nce qib kev txhim kho kev txhim kho kev siv tshuaj thev naus laus zis niaj hnub no.
Nyob rau hauv thaj teb ntawm cov ntaub ntawv sib nqus, gadolinium oxide yog cov khoom siv raw rau kev npaj ntawm cov khoom sib nqus xws li gadolinium hlau garnet (GDIG). Cov ntaub ntawv no ua lub luag haujlwm tseem ceeb hauv cov khoom siv microwave thiab cov khoom siv magneto-optical, thiab muab cov khoom siv rau kev sib txuas lus ntawm niaj hnub no.
Hauv kev siv kho qhov muag, gadolinium oxide yog dav siv nyob rau hauv phosphors, laser ntaub, kho qhov muag thiab lwm thaj chaw vim nws cov khoom kho tshiab. Tshwj xeeb tshaj yog nyob rau hauv kev npaj ntawm siab-refrathaator forms, gadolinium oxide qhia cov txiaj ntsig zoo.
Hauv kev siv hluav taws xob nuclear lub zog, gadolin oxide yog siv los ua kev tswj cov khoom siv Qws Daim ntawv thov no yog qhov tseem ceeb rau kev ua haujlwm nyab xeeb ntawm nuclear reactors.
