- Kutsutsana Kwambiri: Mosiyana ndi zida zapamwamba kwambiri, graphite sikuti sizingofewetsa kutentha, koma mphamvu zake zimachuluka. Pa madigiri 2500 Celsius, mphamvu yowoneka bwino ya graphite ndi kawiri kawiri kutentha.
- Zochita zamatenthedwe komanso zochitika zapamwamba: chifukwa cha kukhalapo kwa maatomu otsalira mu ndege za hexagon mu ndege zapafupi monga ndege za ma mesh pakati pa ndege za ma mesh pakati pa ndege za ma mesh. Thermal mawonekedwe a graphite ndi ofanana ndi zinthu zachitsulo wamba. Ili ndi mawonekedwe apamwamba kwambiri kutentha kwa firiji, koma pamene kutentha kumakulirakulira, kutentha kwa matenthedwe kumachepa. Kutentha kwambiri, graphite ngakhale kumakhala mafuta othandizira.
- Ntchito Yapadera Yapadera: Kukula kwa graphite ndi anisotropic, kotero kuti ma macroscopic owonjezera owonjezera si akulu. Pankhani ya kutentha kwadzidzidzi, kuchuluka kwa graphite sikusintha kwambiri; Kuphatikiza apo, mawonekedwe ake ochititsa chidwi kwambiri amachititsa kuti chidwi chachikulu cha graphite.
- Thuma: Mkati mwa graphite amapangidwa ndi mphamvu ya val der Waal, yomwe ili ndi mphamvu yolimbika ndikupereka mphamvu. Mafuta a graphite zimatengera kukula kwa mbewa zokongola. Okulirapo, ocheperako owoneka bwino, komanso mafuta abwinowo.
- Kukhazikika kwamphamvu kwa mankhwala ndi kukana kwa chipongwe: Graphite imakhala ndi chokhazikika cham'madzi cha firiji ndipo sichimakhudzidwa ndi ma asidi aliwonse olimba, alkali, kapena okhazikika; Ma atomu a kaboni mu graphite wosanjikiza amalumikizidwa mwamphamvu ndi zomangira zotsika, zomwe sizikunyongedwa ndi molten slag ndipo zimatsutsana kwambiri. Komabe, graphite amakonda makutiza makuti, ndi ma oxidation a Antid, ayenera kumwedwa akagwiritsidwa ntchito ngati zida zogwirizana ndi kaboni.
