Fused Aluminum Oxide is most commonly available in Brown-Fused or White-Fused.
Brown-Fused Aluminum Oxide is fused in an electric arc furnace and produces a high strength, tough, and extremely durable grain. GNPGraystar’s Brown Aluminum Oxide is a medium to high density product which is available in standard grades or can be custom graded for your application.
GNPGraystar’s Brown Aluminum Oxide is used in refractories, thermal coatings, and other applications requiring a raw material with high melting point and high toughness.
White-Fused Aluminum Oxide is electrically fused in an arc furnace using Bayer process high purity alumina. The final product is used in applications where higher purity levels and lower iron content is desired as compared to Brown-Fused Aluminum Oxide.
GNPGraystar’s White Aluminum Oxide is used in refractories, thermal coatings, and other applications requiring a raw material with high purity, high melting point, and high toughness.
Typical Properties of Fused Aluminum Oxide:
- High toughness (Mohs 9)
- Chemically inert
- High melting point
