graphite crucible stopper
graphite crucible stopper
(OP)
I'm curious to know more about the graphite crucibles with those spouts at the bottom of the crucible with a graphite rod as a stopper. I know that they are used mostly for casting rare metals. Thus they come pretty small. I would like to use them in a larger application. Is there any video or white paper or anything on how these rod stoppers are used when the material is molten?
Thanks!
Thanks!





RE: graphite crucible stopper
You need to be careful what you melt in them, the clay binder is not compatible with many metals.
That said I have seen similar crucibles in mullite, Al2O3, SiC, and graphite so you have options.
Start with foundry supply shops.
