High-purity α-phase nano alumina powder
Product Features
High-purity nano-alumina powder is prepared using the plasma vapor combustion method, featuring high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low bulk density, easy dispersion, stable crystal phase, high hardness, and excellent dimensional stability. It is used for reinforcement and toughening of various plastics, rubber, and ceramic products, significantly improving the density, smoothness, thermal fatigue resistance, fracture toughness, creep resistance of ceramics, as well as the wear resistance of polymer material products. Additionally, nano-alumina is an excellent far-infrared emission material and is applied in chemical fiber products and high-pressure sodium lamps as a far-infrared emission and thermal insulation material. Furthermore, α-phase alumina has high electrical resistivity and good insulation properties, making it suitable for use in key components of YAG laser crystals and integrated circuit substrates.

Product Applications
1. The main component of both rubies and sapphires is aluminum oxide. Products made from high-purity nano-aluminum oxide powder have fewer impurities, brighter colors, and greater uniformity.
2. Aluminum reacts with oxygen in the air to form a dense layer of aluminum oxide film that covers the surface of aluminum exposed to the air.
3. Aluminum is a good conductor of electricity and heat. The crystalline form of aluminum oxide, due to its high hardness, is suitable for use as an abrasive material and cutting tool.
4. High-purity nano-alumina powder is commonly used as a medium for chromatographic analysis.
5. High-strength alumina ceramics, C substrates, packaging materials, high-purity crucibles, winding shafts, bombardment targets, furnace tubes; polishing materials, glass products, metal products, semiconductor materials, plastics, magnetic tapes, abrasive belts; coatings, rubber, plastic wear-resistant reinforcement materials, water-resistant materials; vapor deposition materials, fluorescent materials, specialty glass, composite materials, and resin materials; catalysts, catalyst carriers, analytical reagents.
6. High-purity nano-alumina powder is used in lighting: as raw material for long-afterglow phosphors and rare-earth tricolor phosphors, high-pressure sodium lamp translucent tubes, LED lights, etc.
Product Characterization
Packaging and Storage
This product is packaged in inert gas-filled plastic bags and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usage effectiveness. Packaging quantities can be provided according to customer requirements, with sub-packaging available.
