Graphite yog cov ntxhia muag muag, dub thiab ib lub ntuj ntawm lub cim carbon monently, suav nrog cov txheej txheem hexagonal uas swb rau kev xav thiab tsis sib txhuam. Nws cov qauv tshwj xeeb ua rau nws yog ib tus neeg saib xyuas hluav taws xob zoo thiab kub, tseem yuav tiv taus cua sov. Feem ntau siv rau graphite thiab xaum "txhuas," refractory cov khoom siv rau cov hluav taws xob, thiab cov khoom siv nres.
Cov khoom ntawm graphite
Softness:Graphite yog cov ntxhia muag heev, tau qhab nia 1-2 ntawm mohs haloness nplai, uas tso cai rau nws txheej kom xaub.
Xim:Nws yog feem ntau grey rau dub nrog nws yog xim hlau lossis npub lus ligter.
Hluav Taws Xob Ua Haujlwm:Graphite yog qhov tsis - hlau uas yog tus neeg ua haujlwm zoo ntawm hluav taws xob thiab cua sov.
Thermal Kuj:Nws muaj lub ntsiab lus zoo heev thiab tuaj yeem tiv taus huab kub tsis tau melting.
Inertness:Graphite yog ze li ntawm cov inert thiab tsis hnov mob nrog feem ntau lwm cov ntaub ntawv.
Tus qauv:Nws cov atoms tau teem nyob rau hauv hexagonal fawm kib sticked lattice, uas muaj txheej ntawm graphene yog pawg ntawm ib leeg.
Kev siv cov graphite
Roj nplua nyeem:Nws cov khaub hlab, flaky Xwm ua rau nws lub roj nplua nyeem zoo heev hauv cov ntawv thov uas ntub cov roj nplua nyeem tsis tuaj yeem siv.
Mem hluav:Qhov muag ntawm graphite yog dab tsi tso cai rau nws siv rau kev sau ntawv thiab kos duab hauv mem hluav.
Refractory:Nws lub peev xwm los ua kom muaj qhov kub ua rau nws muaj qhov zoo rau cov rhuab thiab ua cov crucibles hauv cov pob zeb.
Roj teeb:Graphite yog siv hauv kev tsim cov roj teeb.
Cov kab mob nres:Nws tseem siv rau qee cov kab nres nres.
Metallurgy:Graphite yog siv los ntxiv cov pa roj carbon hlau rau cov hlau thiab hlau nyob rau hauv tus txheej txheem hu ua kev hloov dua siab tshiab.
Dab tsi yog graphite uesd rau?
Graphite yog siv rau hauv xaum, roj nplua nyeem, cov tawv nqaij, foundry cov ntsej muag, txhuam hniav, txhuam, txhuam rau cov hluav taws xob roj, thiab cores ntawm nuclear reactors. Nws cov hluav taws xob siab thiab hluav taws xob ua rau nws tseem ceeb ntawm statmaking, qhov chaw nws yog siv los ua cov electrodes hauv hluav taws xob arc.
Vim li cas graphite yog muaj txiaj ntsig?
Graphite tus nqi qis, thermal thiab tshuaj lom neeg inertness thiab tus yam ntxwv ntawm cov cua sov thiab hluav taws xob pom ntau cov kev siv hluav taws xob thiab cov txheej txheem kub siab.
