Chemically Precipitated Silver Powders

It is a silver powder with a purity of at least 99.9%. By changing the production process we are able to influence the particle size distribution and surface morphology of the prepared powder. It is used in the electrochemical industry for the production of contacts, in the manufacture of cutting tools or for shielding against electromagnetic radiation. The powder is prepared by a controlled chemical reduction of the silver solution in a stirred chemical reactor, followed by a step of modifying the particle size distribution according to customer requirements.
