Cov pas nrig graphite muaj cov thermal conductivity thiab electrical conductivity siab heev, thiab lawv cov electrical conductivity siab dua li cov hlau tsis xeb 4 npaug, siab dua li cov hlau carbon 2 npaug, thiab siab dua li cov hlau tsis yog hlau dav dav 100 npaug. Nws cov thermal conductivity tsis yog tsuas yog tshaj cov hlau, hlau, txhuas thiab lwm yam khoom siv hlau xwb, tab sis kuj txo qis nrog qhov kub thiab txias, uas txawv ntawm cov khoom siv hlau ib txwm muaj. Thaum kub heev, graphite tuaj yeem kub heev. Yog li ntawd, cov khoom rwb thaiv tsev thermal ntawm graphite muaj kev ntseeg siab heev ntawm qhov kub thiab txias heev.
Cov pas nrig graphite feem ntau siv rau kev rho tawm hluav taws xob hauv cov cub tawg kub siab. Qhov kub ua haujlwm siab dua tuaj yeem ncav cuag 3000℃, thiab nws yooj yim kom oxidized ntawm qhov kub siab. Tsuas yog lub tshuab nqus tsev xwb, lawv tsuas yog siv tau rau hauv qhov chaw nruab nrab lossis txo qis.
Vim nws cov khoom zoo heev, graphite siv dav hauv ntau qhov chaw thiab tuaj yeem siv ua cov khoom siv refractory.
Cov khoom graphite khaws cov khoom siv tshuaj qub ntawm cov flake graphite thiab muaj cov khoom siv lubricating zoo. Cov hmoov graphite muaj lub zog siab, tiv taus acid, tiv taus corrosion, tiv taus kub thiab txias.
Graphite muaj kev ruaj khov tshuaj zoo ntawm chav tsev kub thiab tsis xeb los ntawm cov kua qaub muaj zog, cov hauv paus muaj zog thiab cov kuab tshuaj organic, yog li txawm tias siv ntev, qhov poob ntawm cov khoom graphite me me heev, tsuav yog so nws huv, nws zoo ib yam li tshiab.
