Iyo yakajairwa index zvinhu zvewhite fused alumina ialuminium, sodium, potasium, silicon, iron uye zvichingodaro, izvo zvinonyanya kufarirwa uye zvinokurukurwa zvakanyanya zvinofanirwa kuve huwandu hwehuwandu hwesodium, iyo inogona kuonekwa kuti iyo sodium yemukati ine simba guru. pamhando yewhite fused alumina.Parizvino, chena fused alumina pamusika inosiyaniswa ne sodium yemukati, ine sodium yemukati mu 0.35%, sodium yemukati mu 0.3%, sodium yemukati mu 0.2% uye sodium yemukati mu 0.1% yemagiredhi akati wandei, akasiyana zvigadzirwa zvikumbiro zvichave nezvinodiwa zvakasiyana. ye sodium yemukati, saka zvinoenderana neyakasiyana sodium yemukati, inosiyaniswa kubva kune yakajairwa chena fused alumina,low sodium white fused aluminauye micro-sodium chena fused alumina, nezvimwewo.
Iyo sodium mune chena fused alumina inonyanya kutorwa kubva kune sodium oxide inowanikwa muindasitiri alumina.Sodium oxide inoshandiswa mukunyungudutsa kwewhite fused alumina kugadzira yakakwira sodium aluminate kuderedza kugadzirwa kwealumina (α-Al2O3) muwhite fused alumina, zvichikonzera kuderera kwealuminium content uye nokudaro kukanganisa kushanda kwewhite fused alumina.Kudzora kwesodium yakaderera mune chena fused alumina inowedzera nguva yekunyungudika, asi iyo inokonzeresa yekuwedzera mukushandiswa kwemagetsi inowedzera mutengo wekugadzira kunyungudika;kana kushandiswa kwakananga kweyakaderera sodium industrial alumina, asi mutengo wemusika wepasi sodium industrial alumina unodhurawo.
XINLI inogadzira micro-sodiumwhite fused aluminaine sodium oxide inosvika 0.1% kana pasi, iyo inokodzera kugadzira alloy simbi, high hardness simbi, high carbon steel uye zvimwe zvinhu zvine kuoma kwepamusoro uye kusimba kwesimba, uye ine hunhu hwakanaka hwakadai sekuomarara kwepamusoro, kupinza kwakanyanya uye anti- kupisa kugona.
