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-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 ‘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

Chemical Composition

Chemical Composition Na2O % ≤ Al2O3 % ≥ SiO2 % ≤ Fe2O3 % ≤
Gurantee Value 0.06 99.7 0.1 0.05
Typical Value 0.02 99.89 0.04 0.03

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.
