Izinto ezivamile zenkomba ye-alumina emhlophe ehlanganisiwe yi-aluminium, i-sodium, i-potassium, i-silicon, insimbi njalonjalo, okuthandwa kakhulu futhi okuxoxwa ngakho kabanzi kufanele kube inani lokuqukethwe kwe-sodium, okungabonakala ukuthi okuqukethwe kwe-sodium kunomthelela omkhulu kwikhwalithi ye-alumina emhlophe ehlanganisiwe. Njengamanje, i-alumina emhlophe ehlanganisiwe emakethe ihlukaniswa ngokuqukethwe kwe-sodium, ngokuqukethwe kwe-sodium ku-0.35%, okuqukethwe kwe-sodium ku-0.3%, okuqukethwe kwe-sodium ku-0.2% kanye nokuqukethwe kwe-sodium ku-0.1% wamamaki amaningana, izinhlelo zokusebenza zomkhiqizo ezahlukene zizoba nezidingo ezahlukene zokuqukethwe kwe-sodium, ngakho-ke ngokwezinga elihlukile le-sodium, lihlukaniswa ne-alumina emhlophe ehlanganisiwe ejwayelekile,i-alumina emhlophe ehlanganisiwe ene-sodium ephansikanye ne-micro-sodium white fused alumina, njll.
I-sodium etholakala ku-alumina emhlophe ehlanganisiwe itholakala kakhulu ku-sodium oxide etholakala ku-alumina yezimboni. I-sodium oxide isetshenziswa enqubweni yokuncibilikisa ye-alumina emhlophe ehlanganisiwe ukukhiqiza i-sodium aluminate ephezulu ukunciphisa ukukhiqizwa kwe-alumina (α-Al2O3) ku-alumina emhlophe ehlanganisiwe, okuholela ekuncipheni kokuqukethwe kwe-aluminium futhi ngaleyo ndlela kuthinte ukusebenza kwe-alumina emhlophe ehlanganisiwe. Ukulawulwa kwe-sodium ephansi ku-alumina emhlophe ehlanganisiwe kwandisa isikhathi sokuncibilikisa, kodwa ukwanda okubangelwa ukusetshenziswa kukagesi kwandisa izindleko zokukhiqizwa kokuncibilikisa; noma ukusetshenziswa ngqo kwe-alumina yezimboni ephansi ye-sodium, kodwa intengo yemakethe ye-alumina yezimboni ephansi ye-sodium nayo ibiza kakhulu.
I-XINLI ikhiqiza i-micro-sodiumi-alumina emhlophe ehlanganisiweenokuqukethwe kwe-sodium oxide okungu-0.1% noma ngaphansi, okufanelekela ukucubungula insimbi ye-alloy, insimbi yokuqina okuphezulu, insimbi yekhabhoni ephezulu nezinye izinto ezinokuqina okuphezulu namandla okunamathela, futhi inezici ezinhle kakhulu njengokuqina okuphezulu, ubukhali obukhulu kanye nekhono lokulwa nokusha.
