Ytterbium muaj ob peb siv. Nws tuaj yeem ua alloyed nrog stainless hlau los txhim kho qee yam ntawm nws cov khoom siv kho tshuab thiab siv los uatus neeg sawv cev doping hauv fiber ntau optic cable qhov twg nws tuaj yeem siv los ua lub suab nrov. Ib qho ntawm ytterbium's isotopes raug suav hais tias yog qhov chaw hluav taws xob rau cov tshuab X-ray portable.
Yetterbium yog dab tsi?
Kev siv yterbium suav nrog kev siv ua qhov chaw hluav taws xob rau cov tshuab x-ray. Nws yog ntxiv rau stainless hlau los txhim kho nws cov khoom siv kho tshuab. Nws tuaj yeem raug ntxiv ua tus neeg sawv cev doping rau fiber ntau optic cable. Nws yog siv los ua tej yam lasers.
Lutetium siv dab tsi?
Lutetium yog siv hauv kev tshawb fawb. Nws cov tebchaw yog siv los ua tus tswv rau scintillators thiab X-ray phosphors, thiab cov oxide yog siv rau hauv qhov muag qhov muag. Lub caij coj tus cwj pwm zoo li lub ntiaj teb tsis tshua muaj, tsim cov kab sib txuas hauv oxidation xeev +3, xws li lutetium sesquioxide, sulfate, thiab chloride.
Yttrium siv tau li cas?
Yttrium feem ntau yog siv ua ib qho ntxiv hauv cov alloys. Nws nce lub zog ntawm aluminium thiab magnesium alloys. Nws kuj tseem siv los ua cov lim dej microwave rau radar thiab tau siv los ua cov khoom siv hauv ethene polymerization. Yttrium-aluminium garnet (YAG) yog siv rau hauv lasers uas tuaj yeem txiav cov hlau.
Ytterbium feem ntau pom nyob qhov twg?
Ytterbium pom nrog lwm yam tsis tshua muaj hauv ntiaj teb hauv ntau cov ntxhia tsis tshua muaj. Nws yog feem ntaurov qab ua lag luam los ntawm monazite xuab zeb (0.03% ytterbium). Lub ntsiab tseem muaj nyob rau hauv euzenite thiab xenotime. Cov chaw mining tseem ceeb yog Tuam Tshoj, Tebchaws Meskas, Brazil, Is Nrias teb, Sri Lanka, thiab Australia.

Vim li cas ho tshem cov khoom siv tsis siv?
Cov khoom siv tsis siv txuas muaj lub peev xwm los txuag koj cov nyiaj ntawm cov nuj nqis, thiab qhov kev xyaum no tuaj yeem ua rau koj cov khoom muaj sia. Ntau cov khoom koj tau ntsaws rau hauv ib ncig ntawm lub tsev, qhov cuam tshuam rau koj cov cuab yeej yuav ua rau puas tsuaj los ntawm lub zog tsis txaus ntseeg.
Vim li cas cov khoom siv dielectric siv hauv capacitor?
Ib qho khoom siv dielectric yog siv los cais cov paib hluav taws xob ntawm lub capacitor. Cov khoom siv insulating no tseem ceeb txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.
Vim li cas thiaj siv cov khoom siv pseudo tseem ceeb?
Pseudocritical txoj cai muab a txhais tau tias txiav txim siab txo cov khoom sib tov kom cov khoom xyaw ntshiab sib xws hauv cov xeev kev sib raug zoo yuav raug siv los kwv yees cov khoom sib xyaw. Pseudo tseem ceeb yog dab tsi? 2.1 Taw qhia.
Vim li cas dej siv hluav taws xob siv nyob rau sab hnub tuaj ntawm cov andes?
Yuav luag txhua lub nroog loj nyob rau sab hnub poob Pacific txoj kab nqes ntawm Andes vam khom rau dej thiab zog ua los ntawm hydropower, uas lub roob Andes muab (Devenish & Gianella, 2012). Lub Andes yog qhov tseem ceeb raws li qhov chaw muaj peev txheej ntxhia thiab thaj av ua liaj ua teb.
Vim li cas cov alloys siv hauv cov khoom siv hluav taws xob cua sov?
Raws li peb paub alloys muaj siab resistivity thiab siab melting point piv rau cov hlau ntshiab. Yog li cov hlau tsis tuaj yeem yooj yim hlawv lossis oxidize ntawm qhov kub siab dua. Tam sim no raws li peb xav kom kub siab dua hauv cov khoom siv cua sov yog li peb siv cov alloys hauv cov khoom siv cua sov.
