<p>Provided is graphite crucible having the following: a bottom (2); a body (3); a processing part (4) that has an input port (4a); and a gas exhaust port (5) which is closed at the lower end and is open at the upper end side of the body. The graphite crucible can safely, without scattering, melt and solidify an object of processing. Because the graphite is porous, when the graphite is eluted into the object of processing or is worn, the gas within the pores of the graphite passes into the melted object of processing and is continuously released therein as air bubbles. As a result, the gasification of gas that has dissolved in the object of processing can be promoted, and bumping of the object of processing can be prevented.</p> |
