About the "crystallinity" of amorphous Boron, even if it is a glass you
might get some strong and sharp x-ray peaks from the B-B bonds in the
icosahedra of boron atoms. Does anyone know if this is the reason for
seeing strong peaks in the x-ray pattern of amorphous boron?

Actually, I checked out a reference for "amorphous boron", namely the CERAC
catalog. They apparently have a somewhat dubious definition of
crystallinity:
"typ. 5 microns aver. or less (essentially amorphous)"

Re: amorphous boron - at the time that we were looking for appropriate
diluents, we tried several different sources of boron, including some
specifically listed as "amorphous boron". At no time during these tests did
we find any boron that was remotely amorphous. All materials has strong
crystalline peaks and some had very complex XRD patterns, rendering them
unsuitable for use as a diluent.
