      Aluminum Oxide Al2O3 Nanopowder / Nanoparticles

      Aluminum Oxide Nanopowder (Alpha) Products Features:

      α-phase ultrafine Al2O3: phase stability, high hardness, materials with high dimensional stability, it is widely used in a variety of plastics, rubber, ceramics, refractory products for reinforcement toughening, in particular, significantly to improve the ceramic density, finish, thermal fatigue resistance, fracture toughness, creep resistance and wear resistance. As the α-phase ultrafine Al2O3 is a high performance material of far infrared emission, it is widely used in fiber fabric products and high pressure sodium lamp as far-infrared emission and thermal insulation materials. In addition, α-phase nano-Al2O3 with high resistivity and good insulation property, it is widely used as the main components for YGA laser crystal and integrated circuit substrates.

      Aluminum Oxide Nanopowder (alpha) Applications:

      1. transparent ceramics: high-pressure sodium lamps, EP-ROM window;

      2. cosmetic filler;

      3. single crystal, ruby, sapphire, sapphire, yttrium aluminum garnet;

      4. high-strength aluminum oxide ceramic, C substrate, packaging materials, cutting tools, high purity crucible, winding axle, bombarding the target, furnace tubes;

      5.  polishing materials, glass products, metal products, semiconductor materials, plastic, tape, grinding belt;

      6.  paint, rubber, plastic wear-resistant reinforcement, advanced waterproof material;

      7.  vapor deposition materials, fluorescent materials, special glass, composite materials and resins;

      8. catalyst, catalyst carrier, analytical reagent;

      9. aerospace aircraft wing leading edge. 

      Aluminum Oxide Nanopowder (alpha) Dosage: 
      Recommended dosage is usually 1 to 5%, users should be based on different systems to test, and then determine the best dosage for the best use.
