Cov hmoov graphite yog ib hom khoom siv hauv avhmoovnrog cov khoom sib xyaw tseem ceeb. Nws cov khoom tseem ceeb yog cov pa roj carbon yooj yim, uas yog mos, grey tsaus thiab roj. Nws qhov nyuaj yog 1 ~ 2, thiab nws nce mus txog 3 ~ 5 nrog rau kev nce ntawm cov ntsiab lus tsis huv hauv kev taw qhia ntsug, thiab nws qhov hnyav tshwj xeeb yog 1.9 ~ 2.3 Hauv qab qhov xwm txheej ntawm kev cais cua thiab oxygen, nws qhov chaw yaj yog siab dua 3000 ℃, uas yog ib qho ntawm cov peev txheej kub-resistant.
Nyob rau hauv chav tsev kub, txoj kev analytical ntawm kev paub txog tshuaj lom neeg, cov qauv thiab cov khoom ntawmhmoov graphiteNws yog qhov ruaj khov thiab tsis yaj hauv dej, dilute acid, dilute alkali thiab organic solvent. Cov kev tshawb fawb ntawm cov ntaub ntawv tshawb fawb muaj qee qhov kev nyab xeeb ntawm cov khoom siv hluav taws xob uas tiv taus kub siab, uas tuaj yeem siv ua cov ntaub ntawv tseem ceeb rau kev tsim hluav taws, cov ntaub ntawv ua haujlwm conductive thiab cov ntaub ntawv siv roj uas tsis yooj yim hnav.
Thaum muaj qhov kub thiab txias sib txawv, nws ua rau muaj pa oxygen los tsim covcov pa roj carbondioxide lossis carbon monoxide. Ntawm cov carbon, tsuas yog fluorine tuaj yeem cuam tshuam ncaj qha nrog cov pa roj carbon. Thaum cua sov, hmoov graphite yooj yim oxidized los ntawm acid. Thaum kub siab, hmoov graphite tuaj yeem cuam tshuam nrog ntau cov hlau los tsim cov hlau carbides, thiab cov hlau tuaj yeem raug smelted ntawm qhov kub siab.
Hmoov graphite yog cov khoom siv tshuaj lom neeg rhiab heev, thiab nws qhov kev tiv thaiv yuav hloov pauv nyob rau hauv ntau yam xwm txheej.Hmoov graphiteyog ib yam khoom siv hluav taws xob zoo heev uas tsis yog hlau. Tsuav yog hmoov graphite khaws cia rau hauv cov ntaub ntawv rwb thaiv tsev, nws yuav raug them zoo li ib txoj hlua nyias nyias, tab sis tus nqi tsis kam tsis yog tus lej tseeb. Vim tias qhov tuab ntawm hmoov graphite txawv, tus nqi tsis kam ntawm hmoov graphite kuj yuav txawv nrog qhov sib txawv ntawm cov ntaub ntawv thiab ib puag ncig.
