Ponena za kupezeka ndi kugwiritsidwa ntchito kwa Flake Graphite, pali nkhani yolembedwa, bukuli la Shuijing Zhuja linali loyamba, lomwe lili pafupi ndi mtsinje wa Luoshii ". Miyala yonse ili yakuda, chifukwa mabuku akhoza kukhala ochepa, motero amadziwika chifukwa cha grafite yawo. "Zofukula zinthu zakale zikuwonetsa kuti kuyambira koyambirira kwa zaka 3,000 zapitazo kuti alembe mawu a quacacco akum'mawa (ADE 1821-1850) Graphite ngati mafuta, omwe amatchedwa "mafuta kaboni".
Dzina la Chingerezi la Graphite limachokera ku liwu lachi Greek "lopirira", lomwe limatanthawuza "kulemba". Adatchulidwanso ndi katswiri wazamisiri wa ku Germany ndi agralogist agworner mu 1789.
Njira ya molecular ya flake graphite ndi c ndipo ma c ndipoungula wake ndi 12.01. Graphite yachilengedwe ndi chitsulo chakuda komanso chachitsulo cha imvi, chokhala ndi mizere yakuda yakuda, zitsulo zotumphuka. Crystal ndi ya kalasi ya ma shogical a hexilonical a biconol, omwe ali a hertel amalira. Mitundu yofananira imaphatikizapo kufanana ndi mbali ziwiri, hexagal biconical ndi hexagonal, koma mawonekedwe a galasi losowa ndi osowa, ndipo nthawi zambiri amakhala osalala. Magawo: A0 = 0.246nm, C0 = 0.670nm omwe amaphatikizidwa, ndipo mpweya uliwonse umaphatikizidwa ndi kaboni aliyense amakonzedwa mu mphete iliyonse ya hexagonal. Mphete ya hexaloal ya kaboni kwambiri ndi pansi pafupi ndi zigawo zoyandikana zimayang'aniridwa mogwirizana ndi ndege ya mesh kenako ndikulowerera kuti apange mawonekedwe. Mayendedwe osiyanasiyana ndi mtunda wothawa kwawo umatsogolera ku mitundu yosiyanasiyana ya polymorphic. Mtunda pakati pa ma atomu a kaboni kumtunda ndi m'munsi kwambiri kuposa momwe ma atomu a karbon alinso (ma cc kukwirira m'magawo = 0.1420nm pakati pa zigawo = 0.340nm). 2.09-2.23 Kukoka kwamphamvu ndi 5-10m2 / g enieni. Kuumitsa ndi aniotropic, ndege yolunjika yolunjika ndi 3-5, ndi ndege yofananayo ndi 1-2. Nthawi zambiri okalamba nthawi zambiri amakhala ochepera, opusa ndi nthaka. Flaphite Flake ali ndi mawonekedwe abwino komanso othandiza. Flakel flakes nthawi zambiri makamaka opatsirana popaque, yopyapyala yopyapyala ndi yopanda imvi, imaxial, yokhala ndi mndandanda woyenera wa 1.93 ~ 2.07. Powonetsedwa kuti ndi kuwala, imvi, imvi, yowoneka bwino kwambiri, roms imvi, red), kufiyira kwapadera, herteneity yolimba. Zizindikiro: Chitsulo chakuda, kuuma kotsika, gulu la cleavage kwambiri, kusinthasintha, kumverera kosavuta, kosavuta kuyika manja. Ngati zincles Tincles owonongeka ndi Copper Sulfate Yachikulu imayikidwa pa graphite, malo osachikuki amatha kuwongoleredwa, pomwe molybdenite ofanana naye alibe zomwe sizingachitike.
Graphite ndi gawo la ma carbon (maulalo ena 60, kaboni 60, kaboni kaboni Popeza mtundu uliwonse wa kaboni amatulutsa elekitironi, ma elekitoni amenewo amatha kusunthira momasuka, motero Flake graphite ndi ochititsa magetsi. Ndege ya Cleavage imalamulidwa ndi zomangira zazovuta, zomwe zimakhala ndi zosokoneza kukhala mamolekyulu, motero zachilengedwe zimakhala zabwino kwambiri. Chifukwa cha mgwirizano wapadera wa glake graphite, sitingaganize kuti flake glake graphite ndi ukwati wosakwatiwa kapena polycrystal. Tsopano nthawi zambiri zimachitika kuti Flake graphite ndi mtundu wa kristalo wosakanikirana.
