Abstract:
1. A method for producing silver nano-particle material, comprising: providing a precursor material to a crucible on a continuous basis, the crucible being housed in a furnace; heating the precursor material in the crucible to produce a vaporized precursor material; contacting the vaporized precursor material with a process gas in a mixing region to form at least a first portion of silver nano-particle material in the mixing region, the mixing region being in the furnace; drawing a mixture of said first portion, said vaporized precursor material and process gas into an inlet end of a conduit, the process gas cooling the vaporized precursor material to precipitate at least a second portion of said silver nano-particle material in a carrier stream in said conduit; transporting said first portion and said second portion from said conduit in said carrier stream; separating said silver nano-particle material from the carrier stream by filtering; and collecting said silver nano-particle material.
