Graphite hmoov yog hom ntawm cov ntxhia cov khoom sivhmoovnrog cov muaj pes tsawg leeg. Nws lub ntsiab tivthaiv yog yooj yim carbon, uas yog mos, tsaus grey thiab greasy. Nws lub hardness yog 1 ~ 2, thiab nws nce mus rau 3 ~ 5 nrog kev nce lub zog los ntawm kev sib cais yog 1. ℃ ℃, uas yog ib qho ntawm tshav kub-resistant mineral cov khoom siv.
Nyob rau hauv chav tsev kub, qhov ntsuas txoj kev paub ntawm cov tshuaj txuj ci, cov qauv thiab cov khoom ntawmGraphite hmoovyog qhov sib txawv thiab ruaj khov, thiab nws yog insoluble hauv dej, dilute acid, dilute alkali thiab organic kuab tshuaj. Kev tshawb fawb ua haujlwm ntawm cov ntaub ntawv kev tshawb fawb muaj qee cov ntaub ntawv kev nyab xeeb ntawm cov khoom siv kub-cuam tshuam thiab hnav-resistant lubrication cov ntaub ntawv.
Ntawm kev sib txawv kub, nws nyiam nrog oxygen los uapa roj carbondioxide lossis carbon monoxide. Ntawm cov pa roj carbon, tsuas yog fluorine tuaj yeem hnov qab ncaj qha nrog cov roj carbon monoxide. Thaum rhuab, graphite hmoov yog qhov yooj yim dua oxidized los ntawm acid. Ntawm qhov kub thiab txias, cov hmoov graphite tuaj yeem muaj ntau hlau los ua hlau carbides, thiab cov hlau tuaj yeem yog smelted ntawm qhov kub.
Graphite hmoov yog ib tug heev rhiab cov tshuaj lom neeg, thiab nws txoj kev tiv taus yuav hloov raws li cov xwm txheej sib txawv.Graphite hmoovyog ib qho zoo heev uas tsis yog xim hlau cov khoom siv. Raws li ntev raws li graphite hmoov yog muab tso rau hauv cov ntaub ntawv insulating, nws yuav raug them li nyias xaim, tab sis tus nqi tiv taus tsis yog tus lej tseeb. Vim tias cov tuab tuab ntawm graphite hmoov sib txawv, cov tsis kam lees ntawm cov hmoov graphite fab tseem yuav sib txawv nrog qhov sib txawv ntawm cov ntaub ntawv thiab ib puag ncig.
