    Aluminum Oxide Nanopowder (Al2O3, Alpha, 99.9%, 200nm ...
    Nano
    Al2
    O3
     powders (aluminum oxide or alumina) are high-purity (typically >99.9%) ultrafine white powders with particle sizes ranging from
    5
    nm
     to
    1.5
    𝜇
    m
    , commonly used in catalyst carriers, advanced ceramics, and coatings. They exhibit exceptional hardness, thermal stability, and high surface area, particularly in their
    γgamma
    𝛾
    -phase (high activity) or
    αalpha
    𝛼
    -phase (high hardness) forms. 
    Key Types and Properties 
    • Gamma (
      γgamma
      𝜸
      )-phase
      Go to product viewer dialog for this item.
      :       Highly active with a large surface area, ideal for catalysis, desiccant materials, and petrochemical applications.
    • Alpha (
      αalpha
      𝜶
      )-phase
      Go to product viewer dialog for this item.
      :       Stable form with high hardness; used for reinforcing materials, improving ceramic density, and wear resistance.
    • Particle Size & Structure: Available in sizes ranging from 5nm up to 10
      μmu
      𝜇
      m, often sold as dry powder or in liquid dispersions (e.g., in ethanol) for easier handling.       
    Primary Applications 
    • Catalysis: Used as catalytic supports for industrial applications and automotive exhaust purification, including for high-temperature processes.
    • Ceramics and Refractories: Enhances mechanical properties, thermal fatigue resistance, and creep resistance in ceramic manufacturing.
    • Coatings and Textiles: Added to coatings to improve wear resistance, surface hardness, and scratch resistance.
    • Electronics: Utilized in high-pressure sodium lamps and as components for YGA laser crystals.
    • Biomedical: Employed as an antimicrobial agent. 
    Key Suppliers and Forms 
    • Suppliers like
      SSNano
      , Ossila, and US Research Nanomaterials offer various phases, purities, and surface treatments.
    • Available in specialized forms like Zirconia Toughened Alumina (ZTA) for enhanced toughness. 
    Safety Considerations
    Nano-alumina dust can cause respiratory irritation, coughing, and wheezing. Long-term exposure should be avoided as it may cause pulmonary issues like pneumoconiosis.
