micro sodium white fused alumina

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-A_l2O3). 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 ‘three highs’. First, it has a high melting point, Secondly a high density, and thirdly a high hardness, as shown in the following table:

Phase	Chemical compositions	Crystal System	Density (g/cm³）	Micro hardness (Kg/mm²)	Melting point (℃)
α-Al₂O₃	Al₂O₃	Hexagonal	4.0	2300	2050
β-Al₂O₃	Na₂O·11Al₂O₃	Trigonal	3.24	1300~1600	1600

Advantages

The micro-sodium white fused alumina improves the melting point, particle density, bulk density, flexural strength, compressive strength, true density, hardness and other properties of white corundum products, laying a solid foundation for the product to enter the high-end market.

Applications

white fused alumina application
grinding
grinding processing

It is suitable for processing alloy steel, high hardness steel, high carbon steel and other materials with high hardness and high tensile strength.
