Cov nqi oxidation poob ntawm cov graphite nthuav dav thiab flake graphite sib txawv ntawm qhov kub sib txawv. Tus nqi oxidation ntawm cov graphite nthuav dav siab dua li ntawm flake graphite, thiab qhov kub pib ntawm tus nqi oxidation poob ntawm cov graphite nthuav dav qis dua li ntawm cov graphite flake ntuj. Ntawm 900 degrees, tus nqi oxidation poob ntawm cov graphite flake ntuj tsawg dua 10%, thaum tus nqi oxidation poob ntawm cov graphite nthuav dav siab txog 95%.
Tab sis nws tsim nyog sau tseg tias piv rau lwm cov ntaub ntawv sealing ib txwm muaj, qhov kub thiab txias pib ntawm oxidation ntawm cov graphite nthuav dav tseem siab heev, thiab tom qab cov graphite nthuav dav raug nias rau hauv cov duab, nws tus nqi oxidation yuav qis dua vim yog qhov txo qis ntawm nws lub zog nto.
Hauv cov pa oxygen ntshiab ntawm qhov kub ntawm 1500 degrees, cov graphite nthuav dav tsis hlawv, tawg, lossis dhau los ua cov kev hloov pauv tshuaj uas pom tau. Hauv cov pa oxygen thiab chlorine kua qis heev, cov graphite nthuav dav kuj ruaj khov thiab tsis tawg.
