Aluminum oxide is widely used as a technical ceramic in components that require hardness, wear resistance, and chemical stability. It is commonly applied in components such as seals, substrates, and protective parts.1 In microelectronics, Al2O3 is used as a dielectric and passivation material in semiconductor devices, where it provides electrical insulation and contributes to device reliability.2 In optical and protective systems, aluminum oxide is applied in thin film coatings primarily as a durable protective layer for optical components.3 Al2O3 also plays an important role in catalysis and catalyst support applications, where thermally stable oxide surfaces are required for chemical and materials processing.4 Al2O3 is also available in α, β, and γ phases, which differ in structure and surface characteristics, allowing selection of the appropriate forms for structural or catalytic applications.1,4

 

","privateComments":"Aluminum oxide is used as filler for bricks, plastics, and heavy clayware. It is also often used as the abrasive component of sandpaper, and an economical replacement for industrial diamonds.","specialNotes":"","specialNotesProduct":false,"sds":"public/sds/Al2O3.pdf","smiles":"","inchi":"","inchiKey":"","molecularWeight":"","iupac":"","eccn":"","hts":"","createdAt":"2023-09-28T17:54:11.000Z","updatedAt":"2026-01-26T20:07:49.425Z","deleted":false,"deletedAt":null,"userChangedById":19,"customContent":"","displayFormula":"","bottomText":"
