Tsawg Sodium Dawb Corundum Tsawg Sodium Alumina / Tsawg Sodium Dawb Corundum Tsawg Sodium Alumina

Tsawg sodium dawb corundum tsawg sodium alumina cov khoom siv dav siv hauv cov khoom siv tshwj xeeb ceramics, cov ntaub ntawv refractory thiab lwm yam. Cov tsis tshua muaj sodium dawb corundum / tsawg sodium alumina Na20 cov ntsiab lus raug txo, uas txhim kho lub melting point, particle ntom, bulk ntom, dabtsi yog khoov zog, compressive zog, muaj tseeb ceev thiab hardness ntawm cov khoom, uas muaj peev xwm ua tau raws li kev siv ntawm refractory thiab ceramic industries. , nthuav dav ntawm kev siv, thiab nteg cov khoom siv hauv paus rau kev txhim kho ntawm cov kev lag luam saum toj no kom siab precision. Tsawg-sodium dawb corundum tsawg-sodium alumina / micro-sodium dawb corundum micro-sodium alumina.

Micro-sodium dawb corundum hais txog dawb corundum uas muaj sodium oxide ntawm 0.01 thiab 0.09%. Nws cov khoom siv raw yog ua tiav alumina. Micro-sodium dawb corundum yog ib yam khoom uas tsis tshua muaj sodium oxide cov ntsiab lus ntawm dawb corundum. Cov ntsiab lus sodium oxide nyob rau hauv ib txwm dawb corundum yog nyob nruab nrab ntawm 0.2-0.6 %.Lub ntsiab ntawm micro-sodium dawb corundum yog -AI2O3.Sodium oxide yog ib qho teeb meem impurity rau dawb corundum. Nws thiab txhuas oxide tsim ß-Al2O3 nyob rau hauv lub molten lub xeev, thiab theamount ntawm tiam nce nrog nce ntawm sodium oxide cov ntsiab lus. ß-Al2O3 muaj qhov qis melting point, tsis tshua muaj qhov ntom ntom, thiab tsis tshua muaj zog. Na20 nyob rau hauv dawb corundum mas tshwm nyob rau hauv daim ntawv ntawm Na2O 11AL203 (B-Al2O3). Yog hais tias cov alumina raw khoom muaj ntau tshaj 0.6% sodium oxide, cov dawb corundum uas ua los ntawm nws yuav muaj ntau tshaj 10% - Al2O3 Piv nrog - AI203, -AI203 muaj qhov qis melting point, qis dua, thiab qis hardness, raws li qhia hauv cov lus hauv qab no.
