Graphite ndi amodzi mwa mchere wofewa kwambiri, allotrope wa elemental carbon, ndi mchere wa crystalline wa zinthu za carbonaceous. Mapangidwe ake a crystalline ndi mawonekedwe a hexagonal layered; mtunda pakati pa wosanjikiza mauna aliyense ndi 340 zikopa. m, katayanitsidwe ka maatomu kaboni mu maukonde wosanjikiza womwewo ndi 142 picometers, wa hexagonal kristalo dongosolo, ndi wathunthu wosanjikiza cleavage, cleavage pamwamba amalamulidwa ndi mamolekyu zomangira, ndi kukopa kwa mamolekyu ndi ofooka, kotero kuyandama kwake kwachilengedwe Kwambiri. zabwino; periphery ya atomu iliyonse ya kaboni imalumikizidwa ndi maatomu ena atatu a kaboni ndi kulumikizana kogwirizana kuti apange molekyulu ya covalent; popeza atomu iliyonse ya kaboni imatulutsa electron, ma elekitironiwo amatha kuyenda momasuka, choncho graphite ndi kondakitala, Ntchito za graphite zikuphatikizapo kupanga pensulo ndi mafuta odzola, mwa zina.
Mankhwala a graphite ndi okhazikika kwambiri, choncho graphite ingagwiritsidwe ntchito monga pensulo, pigment, polishing agent, etc., ndipo mawu olembedwa ndi graphite akhoza kusungidwa kwa nthawi yaitali.
Graphite ali ndi katundu wa kukana kutentha kwambiri, kotero angagwiritsidwe ntchito ngati zinthu refractory. Mwachitsanzo, ma crucibles omwe amagwiritsidwa ntchito m'makampani opanga zitsulo amapangidwa ndi graphite.
Graphite angagwiritsidwe ntchito ngati zinthu conductive. Mwachitsanzo, ndodo za kaboni m'makampani amagetsi, ma elekitirodi abwino a zida zaposachedwa za mercury, ndi maburashi onse amapangidwa ndi graphite.
