In Reply to: E-Beam crucible liner for aluminium posted by chandana on 06/07/02 at 12:21 AM:

no it will alloy. use graphite or coated graphite and plan on throwing them away often -or- use boron nitride and plan on throwing them away less often. aluminum is very reactive when molten and will in time destroy any liner used. You can evaporate without a liner although it will not be very stable and will getter any oxegen in the system. remeber to never overfill a liner with aluminum or it will crack fill to ~70% of the liner volume.

good luck,
jim
