description Product Description
Aluminum oxide (Al₂O₃), also known as alumina, is a versatile compound with numerous industrial applications.
- Abrasive and polishing: Used as an abrasive in sandpapers, grinding wheels, cutting tools, and polishing compounds due to its exceptional hardness (Mohs scale 9).
- Chemical processing: Serves as a catalyst support in various chemical reactions, including petroleum refining and organic synthesis.
- Protective coatings: Applied as a wear- and corrosion-resistant coating on surfaces, often via plasma spraying or chemical vapor deposition.
- Electronics: Utilized in electronic substrates, insulating materials, and thermal management components due to its high thermal conductivity and electrical insulation properties.
- Biomedical: Employed in implants, prosthetics, and bioceramics for its biocompatibility and strength.
- Filtration: Used in filtration media to remove impurities from gases and liquids.
- Refractories and ceramics: Key component in high-temperature ceramics, refractories, electrical insulators, and fire-resistant containers for enhanced strength and thermal resistance.
- Aluminum production: Essential raw material in the electrolytic production of aluminum metal via the Hall-Héroult process.
- Aerospace: Incorporated into ceramic fibers and heat-resistant composites for aerospace applications.
