Graphite yog ib qho ntawm cov ntxhia mos tshaj plaws, ib qho allotrope ntawm cov pa roj carbon monoxide, thiab cov pob zeb crystalline ntawm cov ntsiab lus carbonaceous. Nws crystalline moj khaum yog ib tug hexagonal txheej txheej; Qhov kev ncua deb ntawm txhua txheej mesh yog 340 daim tawv nqaij. m, qhov sib nrug ntawm carbon atoms nyob rau hauv tib lub network txheej yog 142 picometers, teej tug mus rau lub hexagonal siv lead ua system, nrog ua tiav txheej txheej cleavage, lub cleavage nto yog dominated los ntawm molecular bonds, thiab cov attraction rau molecules yog tsis muaj zog, yog li nws floatability heev. zoo; lub periphery ntawm txhua cov pa roj carbon atom txuas nrog peb lwm cov pa roj carbon atom los ntawm covalent bonding los ua covalent molecule; Txij li txhua cov pa roj carbon atom emits ib qho hluav taws xob, cov electrons tuaj yeem txav tau yooj yim, yog li graphite yog tus neeg xyuas pib, Kev siv graphite suav nrog kev tsim cov xaum xaum thiab cov roj nplua nyeem, thiab lwm yam.
Cov khoom siv tshuaj lom neeg ntawm graphite yog qhov ruaj khov heev, yog li graphite tuaj yeem siv los ua xaum xaum, xim xim, polishing tus neeg sawv cev, thiab lwm yam, thiab cov lus sau nrog graphite tuaj yeem khaws cia ntev.
Graphite muaj cov yam ntxwv ntawm qhov kub thiab txias, yog li nws tuaj yeem siv los ua cov khoom siv refractory. Piv txwv li, cov crucibles siv hauv kev lag luam metallurgical yog ua los ntawm graphite.
Graphite tuaj yeem siv los ua cov khoom siv hluav taws xob. Piv txwv li, cov pa roj carbon rods hauv kev lag luam hluav taws xob, qhov zoo electrodes ntawm mercury zoo tam sim no, thiab txhuam hniav yog ua los ntawm graphite.
