Process for coating a sterilizing filter material with silver and product formed thereby

摘要: Processes are described for coating a particulate silver material such as sand or diatomaceous earth with metallic sterilizing water and the like, objective being to produce highly adherent, thin layer of on diatom surfaces. One method comprises mixing filter particles compound in solution, then reducing elemental form particle surfaces by chemical, optical, gaseous means without addition heat. Another sputtering partial vacuum inert atmosphere.
