Tlhaloso ea Sehlahisoa
Khamphani ea rona e fana ka lits'ebeletso tsa ts'ebetso ea ho roala ka SiC ka mokhoa oa CVD holim'a graphite, li-ceramics le lisebelisoa tse ling, e le hore likhase tse khethehileng tse nang le k'habone le silicon li sebetsane le mocheso o phahameng ho fumana limolek'hule tsa SiC tse hloekileng, limolek'hule tse behiloeng holim'a lisebelisoa tse koahetsoeng, li etsa lera la tšireletso la SIC.
Lintlha tse ka sehloohong:
1. Ho hanyetsa mocheso o phahameng oa oxidation:
khanyetso ea oxidation e ntse e le ntle haholo ha mocheso o le holimo ho 1600 C.
2. Bohloeki bo phahameng : bo entsoeng ka ho kenngoa ha mouoane oa lik'hemik'hale tlas'a boemo bo phahameng ba mocheso oa chlorination.
3. Ho hanyetsa khoholeho ea mobu: boima bo phahameng, bokaholimo bo kopanetsoeng, likaroloana tse ntle.
4. Ho hanyetsa kutu: acid, alkali, letsoai le li-reagents tse phelang.
