The Formation of Elongated Iron and Iron-Cobalt Particles by Electrodeposition into Mercury

Abstract

The preparation of 100–300Aå diameter highly elongated fibers of iron by electrodeposition into mercury is described. The mechanism of formation of these fibers is deduced from direct electron microscopic examination of the structures formed during electrolysis. The relations between the structure of these initial fibers, parameters of formation, and ultimate magnetic properties are discussed.
