Abrasive-grade mineral for industries.
Ideal for grinding and polishing.
Fused Alumina is made in an electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.
Fused Alumina, also known as aluminium oxide, is a highly durable material widely used in industries requiring abrasive and refractory solutions. At LKAB Minerals, our fused alumina offers excellent hardness and thermal stability, making it an ideal choice for applications such as sandblasting, grinding, and ceramic production. Its resistance to high temperatures and chemical wear ensures optimal performance in harsh environments like steel plants and foundries. Available in various grades, fused alumina provides consistent quality for critical industrial processes.
Alumina (also known as Corundum or Aluminium Oxide) is the family name for inorganic compounds with the chemical formula Al2O3.
LKAB Minerals offers Brown and White Fused Alumina for the refractory industry. Our range of grades includes:
Other grades are available on request.
Our Alumina product range is available in 25kg paper sacks, 1000kg bulk bags, or as bulk as standard.
Fused Alumina is a high-purity, dense material derived from bauxite or calcined alumina, available in brown and white grades. It is widely used in industries requiring high hardness, thermal stability, and chemical resistance. Some key applications include:
Refractory applications
Ceramics industry
Abrasives & grinding
Surface preparation & blasting
Industrial coatings
Brown Fused Alumina is a dense material produced from bauxite raw material. The end product has a low iron content, making it particularly valuable in refractory applications.
White Fused Alumina is produced by fusing calcined alumina. It is a white, dense mineral with predominantly large Alpha Alumina crystals. With a high purity, high melting point, and a superior hardness, this product is well suited to the refractory and ceramics industries.
Below, you can see the percentages of Aluminium Oxide (Al2O3), Silica Dioxide (SiO2), Titanium Dioxide (TiO2), and Titanium Dioxide (Fe2O3) in our Alumina product range.
| Compound | Brown Fused Alumina | White Fused Alumina |
|---|---|---|
| Al2O3 [%] | 95.38 | 99.60 |
| SiO2 [%] | 0.98 | 0.08 |
| TiO2 [%] | 2.55 | 0.01 |
| Fe2O3 [%] | 0.16 | 0.02 |
