Abstract

Al-MoO₃ nanocomposites were synthesized based on arrested reactive milling. Altering the milling parameters leads to different, scales of refinement in the structure of the reactive nanocomposites. The objective of this work is to determine the range in which the degree of structural refinement can be changed in a controlled manner. The milling intensity was controlled by using different milling media along with varying amounts of process control agent (PCA), XRD, SEM, DSC and wire-ignition tests were performed to analyze the Al-MoO₃ nanocomposites. Results indicate that there is a decrease in the crystallite size with increase in the milling intensity. However increase in milling intensity also stimulates the undesired reaction between Al and MoO₃. Milling conditions resulting in the highest structural refinement and lowest ignition temperatures were identified.
