Does anyone know a good crucible material for gold?
We have been using carbon crucibles for gold e-beaming for a while and
dealing with the subsequent contamination of the gold with carbon by
periodic replacement of the gold. In my effort to switch away from this
practice, I have tried Boron Nitride, and have not liked the results as
it seems that there is a charging issue with the insulating nature of
the nitride. Any suggestions would be greatly appreciated.
