non-spherical fine material
non-spherical fine material
(OP)
Hi all,
Looking for a very small quantity (a gram or less?) of a material that is non-spherical, with a diameter in the range of 1-15um. We're looking at defects in a thin film of Liquid Crystal and would like something besides round latex beads. A rod-shape (d~1-2um, l~5-10um) would be interesting as would a hex-shaped material. Any ideas?
Sorry if this is naive...

One standard our physical testing lab used was a carbon fiber that had a metallic coating. From the windmills of my mind it may have been nickel.
Anecdotal:
At one time asbestos fibers were used.
