Gamma, Size: 50 nm, 20 wt%

Aluminum Oxide (Al2O3) Nanopowder/Nanoparticles Dispersion in Water, Gamma, Size: 50 nm, 20 wt% is a high-purity (99.99%), alpha-phase Aluminum Oxide (Al₂O₃) dispersion featuring 50 nm particles in a stable 20 wt% aqueous medium. This versatile dispersion is engineered to enhance mechanical strength, thermal conductivity, and dielectric properties across demanding sectors, including advanced ceramics, CMP slurries, and battery separator coatings.

Technical Properties

 Applications

• Ceramics: Used as a sintering aid and microstructure modifier in technical ceramics, where gamma-Al₂O₃ enhances densification, reduces grain growth, and improves mechanical integrity at lower firing temperatures.
• Catalysis: Serves as a high-surface-area support for metal catalysts in heterogeneous reactions, particularly in petrochemical and environmental catalysis, due to its thermal stability and porous morphology.
• Coatings: Incorporated into protective and functional coatings to improve hardness, abrasion resistance, and thermal insulation, especially in transparent or thin-film systems where nanoparticle dispersion uniformity is critical.
• Polishing & Abrasives: Applied in precision polishing of optical components, semiconductors, and metals, where controlled particle size and hardness enable uniform material removal and surface smoothness.
• Electronics: Used in dielectric layers, insulating films, and thermal interface materials, where gamma-Al₂O₃ contributes to high breakdown strength, low dielectric loss, and thermal conductivity enhancement.
• Environmental: Explored in water purification and adsorption systems, where its high surface area and surface hydroxyl groups support the removal of heavy metals, fluorides, and organic pollutants.

Production & Customization

While our standard formulation is supplied at 20 wt% concentration, we offer customized production in varying concentrations to meet your specific application requirements. In addition to deionized (D.I.) water, our dispersions can be formulated in 2-Propanol (IPA) or Ethylene Glycol based on your process needs.
