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.

Silver Powder

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.
