  • Factory wholesale White Aluminum Oxide For Grinding Wheel - Micro Sodium White Fused Alumina – Yufa

    Factory wholesale White Aluminum Oxide For Grinding Wheel - Micro Sodium White Fused Alumina – Yufa

    Compared With β-Al2O3 And α-Al2O3 Sodium oxide is a harmful impurity to white corundum. It forms β-Al2O3 with alumina in the molten state, and the amount of production increases with the increase of sodium oxide content. Na2O in white corundum mainly appears in the form of Na2O·11AL2O3 (β-Al2O3). For example, if the alumina raw material contains more than 0.6% sodium oxide, the white corundum produced with it will contain more than 10% β-Al2O3. Compared with β-Al2O3, α-Al2O3 has ‘t...
