Tom qab graphitization, cov khoom siv tau txais kev ruaj khov zoo heev, tiv taus tshuaj lom neeg, thiab kev ua haujlwm kub siab.
Cov qauv fiber porous peb-seem tshwj xeeb muab graphite mos mos ntau qhov zoo:
- Qhov ceev tsawg heev
- Muaj peev xwm rwb thaiv tsev zoo heev
- Muaj peev xwm ua kom sov tsawg
- Kev txiav thiab kev teeb tsa yooj yim
- Kev hloov pauv zoo heev rau cov qauv sib txawv ntawm lub cub tawg
Qhov ceev ntawm graphite mos mos yog kwv yees li ntawm: 0.08–0.15 g/cm³
Vim nws cov qauv porous heev, cov ntaub graphite mos mos muab cov thermal conductivity qis heev thiab kev ua haujlwm zoo heev. Qee cov khoom graphite tuaj yeem ua tiav thermal conductivity nyob ib puag ncig 0.10–0.20 W / m · K nyob ntawm qib thiab qhov kub thiab txias.
