Abstract

Quartz powders prepared by mechanochemical processing in a planetary mill in the presence of FeCl3 or monohydric or dihydric alcohols were found to exhibit magnetic properties. The magnetic susceptibility of milled quartz depends on the milling time and the amount of additions. The material was shown to undergo aging: its susceptibility and electron paramagnetic resonance spectrum vary during storage. The magnetization of quartz is interpreted in terms of Fe-containing clusters present in the amorphized surface layer.
