Puas yog nickel magnetic?
Nws yog ib lo lus nug yooj yim, tab sis ib qho uas feem ntau tsis meej pem.
Nickel yog ib qho kev hloov pauv hlau uas ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam vim nws muaj ntau yam khoom. Ib qho ntawm nws cov yam ntxwv ntxim nyiam tshaj plaws yog nws tus cwj pwm sib nqus, uas ua rau muaj lus nug ntau: Puas yog nickel magnetic los yog nonmagnetic?
Yog tias koj ua haujlwm nrog cov hlau, hlau nplaum, lossis cov khoom lag luam, tej zaum koj yuav pom cov nickel siv hauv cov hlau nplaum, txheej, thiab cov sib nqus sib nqus. Tej zaum koj yuav cia siab tias muaj tseeb lossis tsis yog. Hauv kev muaj tiag, nickel tus cwj pwm sib nqus nyob ntawm cov xwm txheej, qauv, thiab nws ua li cas.
Hauv tsab xov xwm no, koj yuav tau txais cov lus piav qhia meej thiab siv tau ntawm nickel coj li cas hauv thaj chaw sib nqus- thiab vim li cas qhov ntawd tseem ceeb hauv kev siv tiag tiag - ntiaj teb no.
Puas yog Nickel yog hlau nplaum?
Yog lawm, npib tsib xee yog cov hlau nplaum sib nqus hauv ib txwm muaj. Tshwj xeeb tshaj yog, nws yog ferromagnetic, uas txhais tau hais tias nws tuaj yeem nyiam cov hlau nplaum thiab tuaj yeem ua hlau nplaum nws tus kheej.
Hais tias, cov hlau nplaum ntawm npib tsib xee tsis muaj zog npaum li cov hlau. Koj tuaj yeem pom qhov tsis muaj zog rub, tshwj xeeb tshaj yog nyob rau txhua hnub. Nickel coj li cas kuj nyob ntawm tej yam xws li purity thiab qauv. Hauv cov ntsiab lus tswv yim, koj tuaj yeem cia siab tias npib tsib xee los teb rau qhov chaw sib nqus, tab sis tsis yog ib txwm zoo ib yam li cov hlau nplaum ntau dua.
Dab tsi Ua Nickel Sib Nqus ntawm Qib Atomic?
Nickel yog hlau nplaum vim tias nws cov atoms raug teeb tsa li cas. Hauv txhua lub nickel atom, qee cov electrons tsis ua ke. Cov hluav taws xob tsis sib xws no tsim lub sijhawm sib nqus me me.
Thaum ntau cov nickel atoms zaum ze ua ke, cov sij hawm sib nqus me me tuaj yeem ua kab.
Qhov kev sib tw ntawd yog qhov muab nickel nws tus cwj pwm sib nqus.
Cov qauv siv lead ua kuj tseem ceeb. Hauv cov khoom npib tsib xee, cov atoms tau ntim rau hauv txoj hauv kev uas tso cai rau cov sijhawm sib nqus no los txhawb ib leeg es tsis txhob tshem tawm. Thaum cov xwm txheej yog lawm, koj tsis yog tau txais random magnetism; koj tau txais cov lus teb meej, ntsuas tau rau qhov chaw sib nqus.
Thaum twg Nickel Poob Nws Magnetism?
Nickel tsis nyob twj ywm hauv txhua qhov xwm txheej. Feem ntau yog vim li cas nws poob hlau nplaum yog cua sov. Raws li qhov kub nce, qhov kev txiav txim sab hauv uas txhawb cov hlau nplaum yuav tsis ruaj khov.
Qhov kev hloov no tshwm sim thaum npib tsib xee nce mus txog nws qhov kub ntawm Curie, uas yog me ntsis siab dua 350 degree. Lub sijhawm no, thermal zog cuam tshuam nrog kev sib txuam ntawm cov khoom sib nqus hauv cov hlau. Es tsis txhob ua hauj lwm ua ke, cov domains txav randomly, thiab nickel tsis ua zoo li ferromagnetic khoom.
Hauv txhua hnub, cov hlau tseem nyob ntawd, tab sis nws cov lus teb sib nqus ua rau tsis muaj zog heev. Thaum nickel cools down, magnetism tuaj yeem rov qab los, tsuav yog cov khoom siv tsis tau hloov mus tas li los ntawm huab cua kub lossis kev ua haujlwm.
Puas yog Nickel tseem sib nqus hauv Alloys?
Nickel tseem tuaj yeem sib nqus hauv cov alloys, tab sis cov lus teb nyob ntawm seb nws tau tov nrog dab tsi. Thaum npib tsib xee ua ke nrog qee cov ntsiab lus, nws tus cwj pwm sib nqus yuav tsis muaj zog lossis txawm ploj mus.
Piv txwv li, nyob rau hauv ib co stainless hlau, npib tsib xee pab txhim kho lub zog thiab corrosion kuj, tab sis nws kuj yuav txo tau hlau nplaum. Lwm cov nickel-raws li alloys tuaj yeem khaws cov lus teb sib nqus me me. Yog tias koj ua haujlwm nrog cov alloys, nws yog ib qho tseem ceeb uas yuav tsum tau saib tag nrho cov ntsiab lus, tsis yog cov ntsiab lus npib tsib xee, kom nkag siab tias cov khoom yuav ua li cas rau qhov chaw sib nqus.
Nickel vs Lwm Cov Hlau Hlau
Nickel feem ntau piv nrog lwm cov hlau nplaum, tshwj xeeb tshaj yog hlau thiab cobalt. Thaum tag nrho peb tuaj yeem teb rau qhov chaw sib nqus, lawv coj txawv ntawm kev siv tiag tiag. Cov lus hauv qab no muab rau koj pom meej, sab -los ntawm - sab saib.
