Zinthu zodziwika bwino za alumina yoyera yosakanikirana ndi aluminiyamu, sodium, potaziyamu, silicon, chitsulo ndi zina zotero, zomwe zodziwika kwambiri komanso zomwe zimakambidwa kwambiri ziyenera kukhala kuchuluka kwa sodium, zomwe zitha kuwoneka kuti kuchuluka kwa sodium kumakhudza kwambiri mtundu wa alumina yoyera yosakanikirana. Pakadali pano, alumina yoyera yosakanikirana pamsika imasiyanitsidwa ndi kuchuluka kwa sodium, yokhala ndi sodium mu 0.35%, sodium mu 0.3%, sodium mu 0.2% ndi sodium mu 0.1% ya magiredi angapo, ntchito zosiyanasiyana za malonda zidzakhala ndi zofunikira zosiyanasiyana za sodium, kotero malinga ndi kuchuluka kwa sodium kosiyanasiyana, kumasiyanitsidwa ndi alumina yoyera yosakanikirana wamba,alumina yoyera yosakanikirana ndi sodium yochepandi alumina yoyera yosakanikirana ya micro-sodium, ndi zina zotero.
Sodium mu alumina yoyera yosakanikirana imachokera makamaka ku sodium oxide yomwe imapezeka mu alumina ya mafakitale. Sodium oxide imagwiritsidwa ntchito posungunula alumina yoyera yosakanikirana kuti ipange sodium aluminate yambiri kuti ichepetse kupanga alumina (α-Al2O3) mu alumina yoyera yosakanikirana, zomwe zimapangitsa kuti alumina ikhale yochepa ndipo motero imakhudza magwiridwe antchito a alumina yoyera yosakanikirana. Kuwongolera sodium yochepa mu alumina yoyera yosakanikirana kumawonjezera nthawi yosungunula, koma kuwonjezeka kwa kugwiritsidwa ntchito kwa magetsi kumawonjezera mtengo wopanga smelting; kapena kugwiritsa ntchito mwachindunji alumina yotsika ya sodium ya mafakitale, koma mtengo wamsika wa alumina yotsika ya mafakitale ndi wokwera mtengo kwambiri.
XINLI imapanga micro-sodiumalumina woyera wosakanikiranayokhala ndi sodium oxide ya 0.1% kapena kuchepera, yomwe ndi yoyenera kukonzedwa ndi chitsulo chosungunuka, chitsulo cholimba kwambiri, chitsulo cha kaboni wambiri ndi zinthu zina zolimba kwambiri komanso zolimba, ndipo ili ndi makhalidwe abwino kwambiri monga kulimba kwambiri, kuthwa kwambiri komanso kuthekera koletsa kuyaka.
