Hi all: I have been using vitreous carbon crucible liner for Pt e-beam evaporation, and encounted carbon crucible liner cracking and flaking problems. It is both time consuming and costly to recover the Pt left in a cracked carbon cruciable liner. I wonder if there are other options here, like -- directly putting Pt on Cu hearth or -- using tungsten cruciable liner or other liners instead of vitreous carbon. I would appreciate your help.
