Qhov yug thiab hom graphite
Nyob rau hauv ancient sij hawm, ib tug loj tus naj npawb ntawm cov nroj tsuag algal, microscopic paleontological tseem nyob rau hauv lub primitive oceans, thiab lwm yam carbonaceous residues tsim ib tug sedimentary txheej, thiab tom qab ntau pua lab xyoo ntawm kev tsiv teb tsaws, cov pa roj carbon - nplua nuj sedimentary txheej maj mam txav mus rau qhov tob ntawm lub ntiaj teb lub crusted thiab kub siab, thiab ceev ceev fragmentation. Orderly tsim graphite nuclei, thiab tom qab ntawd, maj mam sib sau ua ke thiab loj hlob mus rau graphite crystals.
Nws yog tsim nyog hais tias thee, raws li ib tug txheeb ze ze ntawm graphite, yog tsim los ntawm tib cov ntsiab lus carbon, tab sis thee tsuas yog yuav tsum tau muaj sedimentation los yog tsawg℃ntawm metamorphism nyob rau hauv qhov ntiav ib feem ntawm lub ntiaj teb crust, thiab yog hais tias qhov kub thiab txias tej yam kev mob mus ntxiv, nws kuj yuav tsum tau paub los ntawm kev hloov ntawm cov thee mus rau graphite, piv txwv li, hu metamorphism ntawm qhov kub thiab txias. anthracite thee txaj los ntawm magma intrusion.
Graphite ore feem ntau tshwm sim li graphite schist, graphite gneiss, graphite -cov kabmob schist thiab metamorphic shale thiab lwm yam ores.
Raws li qhov sib txawv hauv daim ntawv crystallization, graphite tuaj yeem muab faib ua crystalline graphite thiab cryptocrystalline graphite. Crystalline graphite siv lead ua zoo dua, cov muaju pom ntawm qhov muag liab qab, ib txheej ntawm graphite stacked nyob rau hauv ib qho kev txiav txim, uas yog, tsim cov ntses nplai- zoo li cov nplai ntawm graphite.
Cryptocrystalline graphite crystals yog me me thiab lub ntiaj teb nyob rau hauv cov duab, uas tsuas pom tau nrog kev pab los ntawm ib tug electron microscope, yog li nws kuj hu ua earthy graphite. Daim ntawv siv lead ua ntawm graphite yog ze ze rau nws cov nqi lag luam. Feem ntau hais lus, qhov zoo dua qhov℃ntawm crystallization, siab dua nws cov yam ntxwv zoo, yog li ntawd, cov nplai graphite feem ntau muaj cov yam ntxwv zoo thiab daim ntawv thov tus nqi tshaj li lwm hom graphite.
