Xa kucetywa ukuthi zifudunyezwa, ixesha lokuhlala lide kakhulu kubushushu obuphezulu, ioksijini kwiziko kunye neoksijini kumphunga wamanzi zidibanisa neeatom zentsimbi zibizwa ngokuba yi-oxidon. I-fussion eyenziwe ngentsimbi ye-oxide kumphezulu wolusu lwentsimbi, njengokunyanzelwa ngaphambi kokuzisusa, kuya kucinezelwa, okanye emva kokuthathwa kwesagukuqinisa umphezuluUkugungxula, kubaluleke kakhulu xa ubukhulu be-geometry, isibonelelo somatshini, okanye isiphumo sobuso obunganelanga kwaye senze amalungu anobuso obumnyama kwi-scrap, kuya kuba nefuthe ekuchazeniUKUZIPHATHA KAKHULU.

Iindlela zokuthintela i-oxidation zezi:
