Q:
What are some important factors
to know about Particle Characterization?





A:
  • Individual particles and small groups by light
    or SEM microscopy with EDAX and bulk chemistry

  • Small samples = poor statistics!

  • Check the morphology of particles.

  • Groups of particles and size distribution.

  • Can sometimes do microscopy - but
    take many different samples if looking for
    particle sized distribution

  • Process is time consuming if looking for
    particle sized distribution.

  • Must check for agglomeration or preferred
    orientation

  • Can use microscopy/FTIR combination very
    effectively here.
