Ball Milling Synthesis of Al (1050) Particles: Morphological Study and Particle Size Determination

Abstract

The milling characteristics of Al alloy containing 0.1% carbonised coconut shell was investigated. Milling duration up to 40 hours was adopted. Ball milling was carried out at 195 rpm of vial rotation and 8.5 charge ratios. Scanning electron microscope analysis was carried out before and after milling to study effect of ball milling on morphology and size of Al (1050) particles. Results revealed that a minimum particle size of 22.6µm was achieved. The synthesised Al (1050) particles can serve as initial powders for the synthesis of their nanoparticles and microfillers in polymer for polymer composite production for wear resistant and other engineering applications.
