<p>There is provided a graphite crucible including a bottom part (2), a body part (3), a treatment part (4) including an input port (4a), and a gas discharge part (5) that is closed at a lower end side and is opened at an upper end side of the body part. Since graphite is porous, at the time when graphite is eluted into an object to be treated or is consumed, a gas in the pores of a graphite crucible is released as air bubbles continuously into the molten object to be treated. Therefore, gasification of a gas dissolved inside the object to be treated can be enhanced, and bumping of the object to be treated can be prevented.</p> |
