Black Fused Alumina
Black Fused Alumina is a specialized type of fused alumina with a distinct black color. It is made by high-temperature smelting of selected bauxite ores and coal as reducing agents. This material exhibits high hardness, excellent thermal stability, and good electrical conductivity. It is commonly used in applications such as surface preparation, sandblasting, and polishing for its abrasive properties. Black Fused Alumina is known for its low iron content, making it suitable for applications where iron contamination must be avoided, such as the manufacturing of high-quality refractories and abrasive products.
