Because of its remarkable hardness and chemical durability, corundum—a crystalline form of aluminum oxide (AlO₃)—is a valuable material in industrial applications, especially as an abrasive. In this role, corundum is employed as follows:
1. Abrasive Products
Because corundum is so hard—second only to diamond—it is perfect for abrasive applications. Industrial corundum is frequently made artificially and sold as alumina-based abrasives in a variety of grades and shapes.
Wood, metal, and plastics can be polished, smoothed, or shaped with sandpaper, which is made from corundum particles imbedded in paper or fabric.
Corundum is used as a cutting medium in grinding wheels, which are used to machine metal or sharpen tools.- Polishing Compounds: Metal, glass, and gemstone polishing pastes and compounds are made from finely powdered corundum.
- Abrasive Blasting: Corundum is a common substance used in sandblasting to remove impurities, paint, and corrosion from surfaces.
2. Cutting Tools
Corundum abrasives are used to produce:
- Cut-off Wheels: Designed to cut through metals, ceramics, and concrete.
- Saw Blades and Drill Bits: Coated with corundum to enhance cutting efficiency in hard materials.
3. Refractory Applications
Corundum is often integrated into refractories that withstand high temperatures and abrasion. In these applications:
- It serves as a lining material in kilns, furnaces, and incinerators, where both wear resistance and thermal stability are critical.
4. Wear-Resistant Coatings
Corundum is added to wear-resistant coatings on industrial machinery to protect surfaces from abrasion and prolong equipment life.
5. Grinding and Milling Media
Corundum is shaped into balls, rods, or other media for use in grinding mills, which process minerals, pigments, and other fine powders.
1.Hardness: It may cut or wear down the majority of other materials due to its Mohs scale grade of 9.
2. Thermal Stability: It is appropriate for high-friction processes because it retains structural integrity at high temperatures.
3. Chemical Resistance: Corundum is durable in severe settings because it does not readily react with acids, bases, or other chemicals.
4. Customizable Properties: The grain size and purity of corundum can be controlled through synthetic manufacturing to meet certain industrial requirements.
