Al nano and micro particles are flammable, Tend to have high oxidation.
There are at least three ways to do particle size analysis:
1. Microscopy with either hand measurements, or with computer software that can recognize the desired particles and measure them. This is a static system.
2. With laser scattering (Mie Calculations), based upon free-falling particles.
3. With particle shape analyzers which work something like laser scattering (free-falling particles), but rather than a laser and detector, the instrument is equipped with a lens(s) and high-speed camera. Shape and size can be calculated based upon the particle images taken with the high-speed camera. Free-falling allows all possible orientations.
particle size first should be scanned by SEM and the results (pictures) of SEM can be analysed by Image analysis software. This software is free.
Hi dear M.Heydari
Thank you. how do you sample ( Al nano and micro particlec) preparation for SEM analysis?
