High purity α Phase nano alumina powde

  Product features high purity nano aluminum oxide powder is prepared by plasma gas phase combustion method
It has high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low loose density, easy dispersion, stable crystal phase, high hardness and good dimensional stability
It is used to strengthen and toughen all kinds of plastic, rubber and ceramic products, and improve the compactness, smoothness and Cold and hot fatigue, fracture toughness, creep resistance and wear resistance of polymer products are particularly significant
As nano alumina is also a far-infrared emission material with excellent performance, it is used in chemical fiber products and high-pressure sodium lamps as far-infrared emission and thermal insulation materials
In addition, & alpha; Phase alumina has high resistivity and good insulation performance
It can be used in the main accessories of YGA laser crystal and integrated circuit substrate

Product Application
1
Ruby and sapphire are mainly composed of alumina
The products made of high-purity nano aluminum oxide powder have less impurities, brighter and more uniform color;
2
Aluminum reacts with oxygen in the air to form a dense alumina film covering the aluminum surface exposed to the air;
3
Aluminum is a good conductor of electricity and heat
The crystal form of alumina is suitable for grinding materials and cutting tools because of its high hardness;
4
High purity nano alumina powder is often used as the medium of chromatographic analysis;
5
High strength alumina ceramic, C substrate, packaging material, high purity crucible, winding shaft, bombardment target and furnace tube; Polishing materials, glass products, metal products, semiconductor materials, plastics, magnetic tapes, polishing tapes; Coatings, rubber, plastics, wear-resistant reinforcing materials, water-resistant materials; Vapor deposition materials, fluorescent materials, special glass, composite materials and resin materials; Catalyst, catalytic carrier and analytical reagent;
6
High purity nano aluminum oxide powder is used in lighting: long afterglow phosphor raw materials and rare earth trichromatic phosphor raw materials, high-pressure sodium lamp transparent tube, LED lamp, etc

Packaging storage
This product is packed in plastic bags filled with inert gas, sealed and stored in a dry and cool environment
It should not be exposed to the air to prevent oxidation agglomeration caused by moisture, which will affect the dispersion performance and use effect; The packing quantity can be provided according to the customer's requirements
