Molten Salt Hermetic Sealing without O-ring or Gasket
Hello All,
I have a unique engineering problem to propose to you all. I am working with the storage of some highly reactive molten salt at fairly high temperatures (<400C). While we are not working with a large amount of the salt, keeping it contained within a crucible/vessel is highly important and carries some real material constraints. Right now the design has two graphite/boron nitride plates with a pocket milled into them and a number of screws surrounding the pocket to tightly hold the two plates together and hopefully keep the salt in. BUT, I need a hermetic seal between the two plates and can't use any conventional O-rings or gaskets due to the reactive nature of the salts. I was thinking of trying something where I make a groove in one plate and a mating protrusion in the other and hope that is good enough. Does anyone know if this idea sounds feasible or if there are better routes I should explore? Thanks so much.
