Abstract
A method for stabilization of liquid mercury in which powdered copper particles are cleaned with a chemically reactive fluid suitable for removing surface oxidation from the surface. “Clean” powdered copper particles are mixed with liquid mercury to form a powdered copper/liquid mercury mixture. The mixture is then hardened to form an amalgam. Amalgams in which the amount of mercury is greater than 50% by weight of the total amalgam may be produced in accordance with the method of this invention.
