[China Aluminum Industry Network] Average particle size: 50nm, spherical arc and electric explosion method of the two products. Nano aluminum powder application direction: 1. High-efficiency catalyst: Highly efficient oxidizer, solid fuel added to rockets, greatly improves fuel combustion speed and improves combustion stability. 2. Activated Sintering Additives: AlN powders are mixed with 5~10% nano-aluminum powders to reduce the sintering temperature and increase the density and thermal conductivity of the sintered body. 3. Surface conductive coating treatment of metal and scrap metal: Coating of microelectronic devices is performed under conditions of no oxygen and temperatures below the melting point of the powder. 4. Conductive film, preparation of polishing paste and so on. 5. High-grade metallic pigments, composite materials, aerospace, chemical industry, metallurgy (aluminum pyrometallurgy, steel-making deoxidizers), shipbuilding (conductive coating), refractories (magnesium carbon bricks for steelmaking furnaces), new building materials, and anticorrosive materials.
