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.

  • Abrasive Wheels:</
