Muaj ntau cov ntsiab lus thiab impurities tov nrog cov txheej txheem muaj cov txheej txheem ntawm ntuj ci. Cov ntsiab lus carbon ntawm ntujFig Kas graphiteyog li ntawm 98%, thiab muaj ntau tshaj 20 lwm yam tsis muaj carbon elevents, suav nyiaj rau txog 2%. Nthuav graphite yog ua tiav los ntawm ntuj flake graphite, yog li yuav muaj qee qhov impurities. Lub neej ntawm impurities muaj ob qho zoo thiab qhov tsis zoo. Cov nram qab no editor ntawm cov txiv hmab txiv ntoo ib puagmas yuav piav qhia txog kev cuam tshuam ntawm kev tsis sib haum xeebNthuav Graphite:
1. Qhov zoo ntawm impurities los nthuav graphite
Kev tsis sib xyaw muaj txiaj ntsig zoo rau cov yam ntxwv ntawm kev nthuav qhia graphite.
2. Kev tsis ncaj ncees ntawm cov impurities ntawm nthuav graphite
Qhov tsis zoo yog tias lub neej muaj kev cuam tshuam cuam tshuam rau kev nthuav dav ntawmnpaim, thiab tej zaum yuav ua rau cov txheej txheem corrosion electrochemical. Yog li ntawd, nyob rau hauv cov txheej txheem ntau lawm ntawm kev nthuav dav graphite, nws yog meej meej tau hais tias qhov kev thov kom tuag rau ntawm lub ntsej muag ntsuab graphite yuav tsum yog kev lim.
Furuite graphite ceeb toom txhua tus neeg uas impurity cov khoom sib xyaw nrog graphite ore tuaj yeem tshem tawm yooj yim hauv cov kua qaub kho thiab tu theem. Lub impurity eledded nyob rau hauv nruab nrab ntawm graphite txheej lossis retecting intercaser tebchaw yog decomposed, volateding interansion, thiab txog 0.5% ntawm lawv yog oxides thiab silicates. Txawm li cas los xij, lwm cov ntsiab lus tau qhia los ntawm cov kua qaub thiab dej hauv cov txheej txheem ntau lawm.
