Abstract
Mixtures of magnetite and zinc powders were milled for up to 540 minut es and the development of the system was followed using X-ray diffract ion, Mossbauer spectroscopy, and magnetic measurements. The process ta kes place in two overlapping steps. During the first hour of milling, a nonmagnetic intermediate mixed oxide phase forms which decomposes in to ZnO and Fe upon further milling. The freshly formed iron particles are supersaturated with Zn.
