A GRAPHITE CRUCIBLE FOR ELECTROMAGNETIC INDUCTION MELTING SILICON AND APPARATUS FOR SILICON MELTING AND REFINING USING THE GRAPHITE CRUCIBLE |
摘要 |
<p>Disclosed herein are a graphite crucible for electromagnetic induction-based silicon melting and an apparatus for silicon melting/refining using the same, which performs a melting operation by a combination of indirect melting and direct melting. The crucible is formed of a graphite material and includes a cylindrical body having an open upper part through which a silicon raw material is charged into the crucible, and an outer wall surround by an induction coil, wherein a plurality of first slits are vertically formed through the outer wall and an inner wall of the crucible, and a plurality of second slits are vertically formed from an edge of a disc-shaped bottom of the crucible toward a center of the bottom.</p> |
