Introduction about nano metal uses

Use iron, cobalt, nickel and its alloy powder produce magnetofluid with good performance, can be widely applied to seal damping, medical equipment, sound regulation, light display and so on. Metallic nano powders to electromagnetic waves special role in the absorption. Iron, cobalt, zinc oxide powder and carbon-coated metal powder can be used as military stealth materials with high performance millimeter wave, visible light - the invisible material of infrared stealth materials and structures, as well as mobile phone radiation shielding materials.

Copper powder used for the surface of the metal and nonmetal conductive coating. Nano-aluminum, copper, nickel powders have a high activation surface, under anaerobic conditions can be implemented at a temperature lower than the powder melting point of the coating. This technology can be applied to the production of microelectronic devices. Nano-powder is used as a catalyst of copper and its alloys, high efficiency, high selectivity, and can be used in the course of the reaction of the carbon dioxide and hydrogen, methanol synthesis catalyst. Use copper nanoparticles produce precious metal powders to produce superior performance electronic slurry, can greatly reduce the cost. This technology can promote the further optimization of the microelectronics technology.

Iron powder used in high-performance magnetic recording material. Use the high coercive force of nanoscale iron, saturation magnetization (up 1477km2/kg) and signal-to-noise ratio high and good oxidation resistance, etc., can greatly improve the performance of the tape and large-capacity hard and soft disk. Metallic nano powders have special role in the absorption of electromagnetic waves. Use the characteristics of nanoscale iron a high saturation magnetization and high magnetic permeability can be made permeable slurry for Narrow head bond structure. Some nanoparticles are magnetic, use it as a carrier made directing agent, allows fixed lesion gathered in vivo topical drugs under the role of the external magnetic field, so that treat pathological position with high concentrations of the drug, particularly suitable for cancer, tuberculosis diseases.

Nickel powder magnetic fluid. The performance of the magnetic fluid produced by iron, cobalt, nickel, and their alloy powder is good, widely used in the sealing damping, medical devices, sound adjustment, optical display. Due to huge surface area and high activity, nano-nickel powder has a strong catalytic effect, can be used in the hydrogenation reaction of organic matter, such as automobile exhaust processing. Nano-nickel powder added to the solid fuel rocket propellant can greatly improve the heat of combustion of the fuel, combustion efficiency, improve combustion stability. Electronic suspensions are widely used in the microelectronics industry wiring package connection, plays an important role in the miniaturization of microelectronic devices. Use nickel, copper, aluminum nano powder made of electronic slurry, superior performance, good for conducive line further miniaturization. Nano nickel powder auxiliary plus an appropriate technology, can be manufactured electrodes which having a large surface area, can greatly improve the discharge efficiency. Nano powder due to the large proportion of the surface area and the surface atoms, therefore have a high-energy state, the sintering ability is stronger at the lower temperature, is an effective sintering additives, can be significantly reduced powder metallurgy products and the sintering temperature of the high temperature ceramic product.

Efficient catalyst zinc powder, zinc and its alloys nano powders used as catalyst, high efficiency, strong selectivity, can be used as carbon dioxide and hydrogen synthesis methanol catalyst in the reaction process.
