Kev sib xyaw:
Synthetic Graphite: Ua los ntawm carbonaceous feedstock los ntawm high-temperature processing, hluavtaws graphite nthuav qhia cov qauv atomic heev. Nws boasts qib purity siab tshaj 99% carbon, nrog rau qhov seem impurities feem ntau muaj tshauv thiab volatile cov ntaub ntawv.
Ntuj Graphite: Muab tau los ntawm cov pob zeb hauv av tshwm sim, ntuj graphite yog tsim los ntawm cov metamorphism ntawm cov khoom siv organic. Nws muaj cov ntsiab lus sib txawv ntawm cov pa roj carbon monoxide, feem ntau yog li ntawm 15% mus rau 95%, nrog rau cov khoom seem muaj xws li cov hmoov tshauv, sulfur, thiab cov kab mob.
Cov txheej txheem tsim khoom:
Synthetic Graphite: Cov khoom siv hluavtaws graphite suav nrog graphitizing carbonaceous cov ntaub ntawv, xws li roj av coke lossis thee tar pitch, ntawm qhov kub siab tshaj 2,500 degree. Cov txheej txheem no ua rau kev sib raug zoo ntawm carbon atoms, uas ua rau muaj cov qauv crystalline zoo heev nrog thermal thiab hluav taws xob conductivity.
Natural Graphite: Extracted los ntawm mines los yog quarries, natural graphite undergoes ob peb txhua yam thiab tshuaj kho mob los txhim kho nws zoo. Cov txheej txheem no muaj xws li milling, flotation, purification, thiab micronization, tso cai rau tshem tawm impurities thiab kho particle loj thiab tis.
Physical thiab Chemical Properties:
Synthetic Graphite: Synthetic graphite muaj lub cev zoo tshaj plaws piv rau nws cov khoom ntuj tsim. Nws ua pov thawj siab ntom ntom, porosity qis, thiab zoo kawg li thermal thiab hluav taws xob conductivity. Tsis tas li ntawd, hluavtaws graphite muaj kev tiv thaiv zoo heev rau tshuaj corrosion, ua rau nws tsim nyog rau kev thov.
Ntuj Graphite: Ntuj graphite nthuav tawm qis dua, porosity dua, thiab nruab nrab thermal thiab hluav taws xob conductivity. Nws cov khoom tuaj yeem sib txawv nyob ntawm lub hauv paus chiv keeb thiab cov txheej txheem ua haujlwm. Txawm hais tias nws yuav tsis muaj qhov ua tau zoo ib yam li hluavtaws graphite, ntuj graphite tseem pom cov ntawv thov dav hauv ntau qhov kev lag luam.
Daim ntawv thov:
Synthetic Graphite: Vim nws cov khoom tshwj xeeb, hluavtaws graphite pom kev siv dav hauv kev lag luam siab heev. Nws yog ib qho tseem ceeb ntawm cov roj teeb lithium-ion, txhim kho lawv lub zog ceev thiab txuas ntxiv lawv lub neej. Synthetic graphite kuj tseem siv rau hauv cov ntawv thov kub xws li crucibles, electrodes, thiab cov khoom cua sov.
Natural Graphite: Ntuj graphite pom daim ntawv thov hauv ntau qhov chaw. Nws yog feem ntau siv los ua cov roj nplua nyeem vim nws tus kheej-lubricating zog. Tsis tas li ntawd, ntuj graphite yog ua hauj lwm nyob rau hauv cov hlau thiab automotive industries rau crucibles, foundry coatings, nres linings, thiab gaskets. Nws kuj ua hauj lwm raws li cov khoom siv anode hauv alkaline roj teeb thiab hauv nuclear reactors ua tus tswj xyuas.
