Zvinhu zvemazuva ano zve alumina chena yakasanganiswa zvinosanganisira aluminium, sodium, potassium, silicon, iron nezvimwewo, izvo zvinonyanya kufarirwa uye kukurukurwa zvakanyanya zvinofanira kunge zviri huwandu hwesodium, izvo zvinogona kuonekwa kuti sodium ine simba guru pamhando ye white fused alumina. Parizvino, white fused alumina mumusika inosiyaniswa ne sodium content, ine sodium content mu 0.35%, sodium content mu 0.3%, sodium content mu 0.2% uye sodium content mu 0.1% yemagiredhi akati wandei, mashandisirwo akasiyana ezvigadzirwa achave nezvinodiwa zvakasiyana zve sodium content, saka zvichienderana ne sodium content yakasiyana, inosiyaniswa ne white fused alumina yakajairika,alumina chena yakasanganiswa ine sodium yakadererauye micro-sodium white fused alumina, nezvimwewo.
Sodium iri mu alumina chena yakasanganiswa inotorwa zvakanyanya kubva ku sodium oxide inowanikwa mu industrial alumina. Sodium oxide inoshandiswa mukunyungudutsa kwe white fused alumina kugadzira sodium aluminate yakawanda kuderedza kugadzirwa kwe alumina (α-Al2O3) mu white fused alumina, zvichikonzera kudzikira kwe aluminium uye zvichikanganisa mashandiro e white fused alumina. Kudzora sodium shoma mu white fused alumina kunowedzera nguva yekunyungudutsa, asi kuwedzera kwekushandiswa kwemagetsi kunowedzera mutengo wekugadzirwa kwe smelting; kana kushandiswa zvakananga kwe low sodium industrial alumina, asi mutengo wemusika we low sodium industrial alumina unodhurawo.
XINLI inogadzira micro-sodiumalumina chena yakasanganiswaine sodium oxide ye0.1% kana pasi, iyo yakakodzera kugadzirisa simbi ye alloy, simbi yekuomarara kwakanyanya, simbi ine kabhoni yakawanda nezvimwe zvinhu zvine kuomarara kwakanyanya uye simba rekudhonza, uye ine hunhu hwakanaka hwakadai sekuomarara kwakanyanya, kupinza kwakanyanya uye kugona kudzivirira kupisa.
