Abstract:
1. A method for producing a stable, sub-colloidal, nano-phase silver metal hydrosol comprising the steps of: providing a vessel having an opening; placing distilled water as a working fluid in said vessel; providing a moveable wire-shaped electrode constructed from 99.9995% purity silver metal above said vessel and above said working fluid; immersing a plate-shaped electrode constructed from 99.9995% purity silver metal in said working fluid, said plate-shaped electrode completely immersed in said working fluid, from between 0.50 inches and 0.75 inches beneath the surface of said working fluid; providing a transformer; connecting a first shielded electrical lead having a first end to said transformer; connecting a second end of said first shielded electrical lead to said wire-shaped electrode; connecting a second shielded electrical lead having a first end to said transformer; connecting a second end of said second shielded electrical lead to said plate-shaped electrode; passing a 14,000-18,000 Volt alternating current from said transformer to establish a discharge arc between the silver wire-shaped electrode above the working fluid and plate-shaped electrode immersed in the working fluid wherein the separation distance of said arc is between 1.25 and 1.50 inches, said separation distance defining the distance between said wire-shaped electrode and said plate-shaped electrode; and producing subcolloidal sized silver metal particles in said working fluid from said discharge arc and said wire-shaped electrode and said plate shaped electrode.
