Silver Nanopowder

Silver Nanopowder

Silver nanopowder for sale is typically by laser evaporation in vacuum or in a small pressure of gas to get 10 to 100 nm diameters. It can be divided into nano flake silver powder and nano spherical silver powder. Nanomaterials have singular properties that are different from traditional materials in mechanics, electricity, heat, optics, catalysis, etc., which arouse widespread interest and become an important subject in the theoretical research and application development of functional materials with special properties. The physical data of nano-meter silver powder from PAM-XIAMEN- a silver nano powder manufacturer is shown as below:

2. Application of Silver Nanopowder

Silver nanoparticles has the advantages of large specific surface area, large activity, high catalytic activity, low melting point, and good sintering performance based on its small particle size. At the same time, it also retains the good electrical conductivity and antibacterial properties of metallic silver. The bright color makes the nano-silver powder more widely used. The details can be summarized as follows:

Field Applications and Advantages
Conductive Silver Paste Silver paste and various types of conductive polymers. The screen printing has high efficiency, flat conductive tape, and it is not easy to break. It can save 30%~50% of silver consumption; it can be used as carbon film potentiometer, solid tantalum capacitor, composite transistor, special electrode lead of integrated circuit, etc.
Conductive Coating Silver nanopowder is the surface treatment of some components in the electronics industry; the coating is thin and flat, and the conductivity is good; low sintering temperature makes the silver nano powder be used for filters, ceramic tube capacitors, etc.
Catalytic Industry Used in ethylene oxidation catalyst and other chemical synthesis.
Deodorization and Sterilization The disinfection and sterilization of medical gauze will form a series of high-tech industries.
Heat Exchange The silver nanoparticles are used as the insulating wall material for the heat exchanger of the low-temperature He3-He4 dilution refrigeration device, which can lower the temperature from 10mK to 2mK. Sintering silver paste on a single silicon wafer of solar cells can increase the thermal conversion rate.
Energy Industry Main electrode materials for electronic components such as monolithic capacitors, filters, carbon film potentiometers, button capacitors, membrane switches, and semiconductor chips. Ultra-fine silver graphite powder electrode, with a large current density of 468~505A-h-L-1, has the number of cycles as high as 700, and the energy loss is small.
Conductive Paste, Insulating Paste and Dielectric Paste Sintering at low temperature, the substrate does not need high-temperature resistant ceramic materials, and even low-temperature materials such as plastics can be used.
Electroforming Technology The modulated conductive Ag paste can be evenly coated on the wax blank, and the surface is smooth


3. FAQ of Silver Nanopowder

Q:Does the silver power have some fatty acid coating?
When sintering some smoke was released indicating some organic compound was burning.
Can you give me some details over this powder?

A:Yes, normally we supply nanometer silver powder coated with unsaturated fatty acid.
