Abstract: Mechanical plating provides a new technique of manufacturing of certain materials containing multiple elements, including amalgams, and novel pellets containing multiple materials. Some embodiments provide new and versatile materials for dosing mercury, metals or other inorganic compounds into lamps. Some embodiments include materials comprising layers of metals or compounds built up on a substrate. One embodiment is a layer of zinc amalgam applied to a glass sphere. Also disclosed is an improved method of manufacture for such particles that will speed production, increase yields, lower costs and reduce exposure to mercury in the workplace.
