Abstract
This invention provides a double jet process to produce silver nanoparticles, the process comprising providing a double-jet system to form a reaction mixture in a reactor containing the reactor solution by adding a basic aqueous silver ammonia complex solution and a basic reducing solution to the reactor solution at the same controlled rate with a targeted pH profile for the reactor solution from acidic to basic determined by the addition rate and the initial pH of the reactor solution. Use of this process results in a dispersion comprised of silver nanoparticles that have a specific size and de-agglomeration level that is determined by the process conditions.
