Me ntsis sodium dawb corundum hais txog dawb corundum nrog sodium oxide cov ntsiab lus ntawm {{0}}}01 thiab 0.09%, thiab nws cov khoom siv raw yog ua tiav alumina. Me ntsis sodium dawb corundum yog ib yam khoom uas tsis tshua muaj sodium oxide cov ntsiab lus nyob rau hauv dawb corundum, 1 Cov ntsiab lus sodium oxide nyob rau hauv dog dig dawb corundum yog nruab nrab ntawm 0.2-0.6%.

Lub ntsiab theem ntawm corundum dawb yog -Al203.

Sodium oxide yog ib qho teeb meem impurity rau dawb corundum. Nws tsim B-A203 nyob rau hauv lub xeev molten nrog alumina, thiab cov yields nce nrog cov ntsiab lus sodium oxide. B-Al203 muaj cov ntsiab lus melting tsawg, lub cev tsis muaj zog thiab tsis tshua muaj zog. Na20 hauv corundum dawb feem ntau yog nyob rau hauv daim ntawv ntawm NA20-11AL203 (B-A1203). Yog tias cov khoom siv alumina muaj ntau dua 0.6% sodium oxide, cov dawb corundum tsim los ntawm nws yuav muaj ntau dua 1% -Al203
