Lub ntsiab tivthaiv yog carbon (c). Graphite tsim nyob rau hauv qhov yog tsim thaum lub sijhawm txo qis nyob rau hauv high- tej kev mob kub. Graphite yog dav faib vim yog metamorphism, uas yog tsim los ntawm cheeb tsam metamorphism ntawm cov pob zeb sedimentary nplua nuj hauv cov organicace. Piv txwv li, thee seams los yog carbonaceous sedimentary pob zeb tuaj yeem tsim cov ntxhib thiab cov metamorphism; Thaum cov pob zeb magma tuaj rau hauv kev sib cuag nrog cov limestone, CO2 decomposed los ntawm limestone kuj tseem ua tau los ua graphite los ntawm kev txo. Graphite tsis tshua muaj tshuaj ntshiab thiab feem ntau muaj cov tshuab qhuas ntau, xws li, cov pa roj ntsha, thiab lwm yam, h2, ch4, n2, dej, thiab asphalt. Graphite crysted yog ib tug lattice, uas yog tsim muaj ntau lub rings kev ib txwm muaj ntawm cov pa roj carbon monoxide attracts sib txuas nrog rau ib qho kev sib txuam loj, uas yog sib txuam nrog txhua lwm yam. Cov muaj cov muaj cov muaju ntxiv rau cov hexagonal crystal system. Ua tiav cov muaju tsis tshua muaj muaj tsawg thiab feem ntau tshwm sim hauv daim ntawv ntawm daim hlau thiab teev. Amorphous Graphite feem ntau yog nyob rau hauv daim ntawv ntawm lumps thiab hmoov. Thaum lub crystal taub ntawm lub ntuj graphite tsawg dua 1 μm, thiab nws cov ntawv siv ua kom nruj yog tias amorphle graphite lossis amorpholog graphite lossis pob zeb hauv ntiaj teb).
Cov xim ntawm graphite li ntawm hlau grey mus rau hlau grey, nrog dub streaks. Nws muaj qhov muag inomogeneity, hardness inomogeneity, thiab yog opaque thiab muaj xim hlau luster. Achanitic muaju yog npub. Lub Hardness yog 1 txog 2, qhov tshwj xeeb lub ntiajteb tau yog 2.09 txog 2.23, thiab cov kev sib tsoo ntawm cov kab mob qis dua yog 1.84 rau 1.98. (Kev hloov pauv hauv lub ntiajteb txawj nqus yog txiav txim siab los ntawm tus naj npawb ntawm npuas.) Cov ntawv txheeb tau, muaj kev nplua nyiaj, thiab muaj cov ntawv thiab ntiv tes. Graphite muaj cov cua sov ua kom muaj zog (siab dua tooj liab thiab txhuas), thiab tuaj yeem tiv thaiv kom kub siab tshaj 3000 degree. Nws muaj lub ntsiab lus melting ntawm 3800℃thiab lub qhov cub npau npau ntawm 4250 degree. Nws muaj plasticity, muaj zog tshuaj ruaj khov, thiab yog insoluble hauv cov acids thiab alkalis.
1. Kev tsim hluav taws xob smelting rauv, arc teeb thiab cov tshuab hluav taws xob, cov pas nrig carbon ntau rau cov xovtooj, thiab lwm yam.
2. Tsim cov tawv me me me me ntawm cov tawv ntoo.
3. Vim tias graphite tuaj yeem nqus tau ntau ntawm cov neutrons, nws tuaj yeem siv ua tus tswj hwm hauv atomic prystalline graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite.
4. Siv los txheej rau cov xuab zeb casting pwm, anti {{1} Rust txheej, tshuab roj nplua nyeem, thiab cov roj nplua nyeem.
5. Cov khoom sib xyaw ntawm ntau cov ntaub ntawv refractory thiab refractory insulating cov ntaub ntawv.
6. Ua kom corrosion -} tiv taus xim.
7. Ua cov mem hluav ntxiv thiab siv lawv ua cov ntaub ntawv xim dub.
8. Tom qab tshuaj lom neeg tshwj xeeb, nws tuaj yeem ua rau hauv cov khoom sib khi tau yooj yim.
