Mechanochemical Activation of Magnetite Nanoparticles
Source abstract
Abstract
Using Mossbauer spectroscopy as a function of ball milling time, it was found that nanomagnetite behaves differently than magnetite during mechanochemical activation. The phase sequence is determined by the original particle size of the powder. Magnetite suffers a phase transformation to hematite, while nanomagnetite (d = 19 nm) gives rise to superparamagnetism as effect of prolonged milling.
