Graphite hmoov yog ib hom ntxhia hmoov, cov khoom tseem ceeb yog cov roj carbon, nws yog mos, tsaus grey; nws muaj greasy xav thiab yuav kis tau daim ntawv. Lub hardness yog 1-2, thiab hardness tuaj yeem nce mus rau 3-5 nrog qhov nce ntawm impurities nyob rau hauv txoj kab ntsug. Qhov tshwj xeeb lub ntiajteb txawj nqus yog 1.9 txog 2.3. Nyob rau hauv cov xwm txheej ntawm cais cov pa oxygen, nws cov ntsiab lus melting yog siab dua 3000 ℃, uas yog ib qho ntawm cov khoom siv kub-resistant tshaj plaws. Cov khoom siv tshuaj lom neeg ntawm graphite hmoov yog qhov ruaj khov ntawm chav tsev kub, thiab yog insoluble hauv dej, dilute acids, dilute alkalis thiab organic solvents. Cov khoom muaj qhov kub thiab txias tsis kam thiab conductivity, thiab tuaj yeem siv los ua cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov ntaub ntawv hnav-resistant lubricating.
