Iimpawu zesalathiso eziqhelekileyo ze-alumina edibeneyo emhlophe yi-aluminium, i-sodium, i-potassium, i-silicon, isinyithi kunye nokunye, apho eyona nto idume kakhulu kwaye ixutyushwa ngokubanzi kufuneka ibe ngumthamo we-sodium umxholo, onokubonwa ukuba umxholo we-sodium unempembelelo enkulu. kumgangatho we-alumina edibeneyo emhlophe.Okwangoku, i-alumina edibeneyo emhlophe kwiimarike iyahlula ngomxholo we-sodium, kunye nomxholo we-sodium kwi-0.35%, umxholo we-sodium kwi-0.3%, umxholo we-sodium kwi-0.2% kunye nomxholo we-sodium kwi-0.1% yamabanga amaninzi, izicelo ezahlukeneyo zeemveliso ziya kuba neemfuno ezahlukeneyo. kumxholo wesodium, ngoko ke ngokwemixholo yesodium eyahlukileyo, yahlulwa kwi-alumina eqhelekileyo emhlophe,i-alumina ephantsi yesodium emhlophe edibeneyokunye ne-micro-sodium emhlophe edibeneyo ye-alumina, njl.
Isodium kwi-alumina edibeneyo emhlophe iphuma ikakhulu kwi-sodium oxide efumaneka kwi-alumina ye-industrial.I-sodium oxide isetyenziselwa inkqubo yokunyibilikisa i-alumina edibeneyo emhlophe ukuvelisa i-alumina ye-sodium ephezulu ukunciphisa ukuveliswa kwe-alumina (α-Al2O3) kwi-alumina edibeneyo emhlophe, ekhokelela kumxholo ophantsi we-aluminium kwaye ngaloo ndlela ichaphazela ukusebenza kwe-alumina edibeneyo emhlophe.Ukulawulwa kwe-sodium ephantsi kwi-alumina edibeneyo emhlophe kwandisa ixesha lokunyibilikisa, kodwa ukunyuka okubangelwa kukusetyenziswa kombane kwandisa iindleko zokuvelisa ukunyibilika;okanye ukusetyenziswa ngokuthe ngqo kwe-alumina yamashishini e-sodium ephantsi, kodwa ixabiso lemarike ye-alumina ye-sodium ephantsi yoshishino nayo ibiza kakhulu.
I-XINLI ivelisa i-micro-sodiumi-alumina edibeneyo emhlophekunye nomxholo we-sodium oxide we-0.1% okanye ngaphantsi, olungele ukusetyenzwa kwentsimbi ye-alloy, ukuqina kwentsimbi ephezulu, intsimbi ye-carbon ephezulu kunye nezinye izinto ezinobunzima obuphezulu kunye namandla obunzima, kwaye ineempawu ezibalaseleyo ezifana nobunzima obuphezulu, ubukhali obuphezulu kunye ne-anti- ukutshisa amandla.
