LINING FOR SURFACES OF A REFRACTORY CRUCIBLE FOR PURIFICATION OF SILICON MELT AND METHOD OF PURIFICATION OF THE SILICON MELT USING THAT CRUCIBLE (S) FOR MELTING AND FURTHER DIRECTIONAL SOLIDIFICATION |
摘要 |
<p>A crucible for molten silicon comprises at least one refractory material having an inner surface and a lining deposited onto the inner surface, the lining comprising colloidal silica. A method for silicon purification comprises melting a first silicon in an interior of a melting crucible to provide a first molten silicon, the melting crucible comprising a first refractory material having at least one first inner surface defining the melting crucible interior, directionally solidifying the first molten silicon in a directional solidification mold to provide a second silicon, the directional solidification mold comprising a second refractory material having at least one second inner surface defining a mold interior, and coating at least a portion of at least one of the first inner surface and the second inner surface with a lining comprising colloidal silica.</p> |
