Khamphani ea rona e fana ka lits'ebeletso tsa ts'ebetso ea ho koahela SiC ka mokhoa oa CVD holim'a graphite, li-ceramics le lisebelisoa tse ling, e le hore likhase tse khethehileng tse nang le carbon le silicon li arabele mochesong o phahameng ho fumana limolek'hule tsa SiC tse hloekileng haholo, limolek'hule tse behiloeng holim'a thepa e koahetsoeng, li theha lera le sireletsang la SIC.

Likarolo tse ka sehloohong:

1. Khanyetso ea ho chesoa ha oxidation mochesong o phahameng:

Khanyetso ea oxidation e ntse e le ntle haholo ha mocheso o le holimo ho fihla ho 1600 C.

2. Bohloeki bo phahameng: bo entsoe ka ho kenngoa ha mouoane ka lik'hemik'hale tlas'a boemo ba chlorination bo phahameng ba mocheso.

3. Khanyetso ea khoholeho ea mobu: ho thatafala ho hoholo, bokaholimo bo kopaneng, likaroloana tse tšesaane.

4. Ho hanyetsa mafome: asiti, alkali, letsoai le li-reagent tsa tlhaho.
