Product Features

High-purity nano alumina is prepared by plasma vapor phase 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 particularly effective in reinforcing and toughening various plastic, rubber, and ceramic products, enhancing the density, smoothness, thermal fatigue resistance, fracture toughness, and creep resistance of ceramics, as well as improving the wear resistance of polymer materials. Since nano alumina is also an excellent far-infrared emitting material, it is used in chemical fiber products and high-pressure sodium lamps as a far-infrared emitting and insulating material. Additionally, α-phase alumina has high 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 components of ruby and sapphire are alumina. Products made with high-purity nano alumina powder have fewer impurities, brighter color, and more uniform appearance;

2. Aluminum reacts with oxygen in the air to form a dense alumina film that covers the surface of aluminum exposed to air;

3. Aluminum is a good conductor of electricity and heat. Due to its high hardness, alumina in crystalline form is suitable for use as a grinding material and cutting tool;

4. High-purity nano alumina powder is commonly used as a medium in chromatography;

5. High-purity 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, grinding belts; coatings, rubber, plastic wear-resistant reinforcement materials, waterproof materials; vapor deposition materials, fluorescent materials, special glass, composite materials, and resin materials; catalysts, catalyst carriers, analytical reagents;

6. High-purity nano alumina is used in lighting: as raw material for long-afterglow phosphors and rare earth tri-color phosphors, transparent tubes for high-pressure sodium lamps, LED lights, etc.

Product Characterization

Packaging and Storage

This product is packaged in heat-sealed aluminum foil bags and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidation and agglomeration, which may affect dispersion performance and usage effectiveness. Packaging quantities can be customized according to customer requirements, including sub-packaging.
