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.
