Silver Coated Copper Powder Industrial Grade 99.9%

Silver coated copper powder is highly conductive filler, which is a kind of new conductive composite powders. It is stable at room temperature and pressure, which is not easy to oxidize. The resistance is stable too. When adding in coating, glue, ink, polymer paste, plastic and rubber, they are conductive products and electromagnetic shielding products.

Silver Coated Copper Powder

There are different Ag content as 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60% and so on. Different shapes are available too as flake, spherical, dendritic. So particle size does as 325mesh, 400mesh, 600mesh, 800mesh and so on.

Silver Powder Industrial Grade 99.9%

Silver powder is a ultra fine precious metal particles, which has best electrical conductivity and thermal conductivity among all metal elements. Its reflectivity is extremely high, which can reach above 99%. Silver nano powder is insoluble in water, but resolve in dilute nitric acid and hot concentrated sulfuric acid. Its chemical property is stable and doesn’t react with moisture and oxygen in air. Inhaling or touching silver ultra fine powder or smog cause blue grey spot slowly, which would never fade away. Please be cautious when handling. Ultra fine silver powder’s processing is reduction from silver nitrate solution.

Applications

In electronic industry, silver ultra fine  powder applies to prepare sintered conductive paste with high temperature  and conductive coating. It is main conductive content for thick film ink. The silver paste using silver ultra fine powder has many advantages, for instance, good wettability, good printing, excellent sintering film. It applies to make thick film mixture IC, resistor, multi-layer capacitor and sensitive element.

Nano silver powder can apply to conductive magnetic material, high-performance catalyst and antibacterial agent. However sheet silver powder mainly applies to conducting coating layer and conductive pole of low temperature silver paste.

Silver powder also can apply to process alloys, high pure silver salts and high pure analytical reagents. It is for coating silver and doping.
