Dense fused alumina, also known as dense aluminum oxide, is a high-quality abrasive material made from aluminum oxide. It is produced through a process called fusion, where alumina (Al2O3) is melted and then rapidly cooled to form hard, dense crystals. This results in a material with excellent hardness, toughness, and abrasive properties.
Dense fused alumina is commonly used in various industrial applications, including:
Abrasive Blasting: It is used as a blasting abrasive in sandblasting and shot peening operations to clean, prepare, or finish surfaces. Its hardness and durability make it effective for removing rust, paint, and other coatings.
Grinding and Polishing: Dense fused alumina is used as a grinding and polishing abrasive for metals, ceramics, glass, and other materials. It can produce a smooth and reflective surface finish.
Refractories: In the production of refractory materials, dense fused alumina is used as a raw material. It provides high-temperature resistance and is used in the construction of furnaces, kilns, and other high-heat applications.
