Saj siab graphite ntawv yog tsis tsuas yog siv rau kev sib khi, tab sis kuj muaj hluav taws xob ua haujlwm, thermal, siab thiab tsis muaj xeb. Vim tias qhov no, kev siv cov graphite yoog tau tau nthuav dav tau ntau xyoo. Cov khoom siv hluav taws xob cua sov yog ua los ntawm nws conductivity thiab ua haujlwm, thiab nws yooj yim mus nias cov kev coj ua Grastex cov roj av roj thiab oxidant roj. Cov hauv qab no cov kab ke cog lus yuav teb yog vim li cas thiaj yooj yim graphite daim ntawv yog ib qho insulator zoo:
Cov yam ntxwv zoo tshaj plaws ntawm daim ntawv yooj yim graphite ntawm thermal hluav taws xob kev xav, cov ntaub thaiv npog (rwb thaiv tsev). Rau cov cua sov kub (> 850 ℃), hloov yooj yim graphite yog cov kev ua tau zoo tshaj plaws li tungsten thiab molybdenum. Graphite tau ntev tau siv raws li kev kub siab loj, thiab yoog raws graphite ntawv ci yog ib qho zoo heev follower. Thaum siv nyob rau hauv qhov kub siab tuag xws li tuag forging, nws muaj covricity zoo, thiab tuaj yeem zam dhau lub raum tuag, nrog cov nyhuv zoo. Lwm cov kev siv tshiab kuj tau tsim kho.
Daim ntawv graphite tsim los ntawm cov txiv hmab txiv ntoo graphite yog ua los ntawm cov khoom siv raw rau hauv cov ntaub ntawv tshwj xeeb, uas tuaj yeem tsuas yog tsim los ntawm cov ntawv graphite cov ntawv tsim khoom. Daim ntawv graphite yog yooj yim rau kev txiav thiab tuaj yeem txiav mus rau hauv ntau daim duab ntawm cov ntxig graphite, uas tuaj yeem siv rau hauv cov teb ntawm kev lag luam sealing. Cov ntawv sib khi zoo ntawm graphite tau ua nws lub koob npe nrov ntawm "King of Sealing", thiab graphation ntawv tuaj yeem siv rau hauv kev siv tshuab sealing, thiab lwm yam.
