Ball milling-induced reduction of MoS2 with Al

The ball milling-induced reduction of MoS2 by Al has been investigated. Although this is a highly exothermic reaction that, based on its thermodynamic properties, should progress as a self-sustaining process, ignition could not be achieved by ball milling. In order to identify the reason, XRD, particle size distribution, SEM, and DTA measurements were carried out on a series of samples milled for different durations. It was found that the largest composite agglomerates broke up due to the presence of a fine dispersion of MoS2 particles. SEM also revealed that the grains are packed rather loosely within the agglomerates. These results indicate that a self-sustaining process can take place only if large and well-compacted composite particles are present.

One of the authors (A.R.T.) is expressing his thanks to the Council for International Exchange of Scholars for a Fulbright Scholarship that made this investigation possible. This work was supported in part by DRIF funds from the University of Maryland, Baltimore County. The help of Dr. Robert C. Reno with the SEM investigations and the ball milling experiments carried out by Youssef A. Mahmoud are greatly appreciated.
