Indlela yokususa i-oxidation ichazwe ngolu hlobo lulandelayo: FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha i-nitrogen ngobuninzi obaneleyo ukubopha i-nitrogen ekhoyo (umz. ubuncinci be-0,020 % iyonke ye-Al okanye i-0,015 % ye-Al enyibilikayo).b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ulwakhiwo lweekhemikhali lubonisa umxholo we-Al ophantsi we-0,020 % kunye nomlinganiselo ophantsi we-Al/N we-2:1, okanye ukuba kukho ezinye izinto zokubopha i-N ezaneleyo. Izinto zokubopha i-N mazirekhodwe kwiXwebhu loHlolo.
