METHOD FOR THE PRODUCTION OF SILICON SUITABLE FOR SOLAR PURPOSES |
摘要 |
<p>The method involves fusing a metallurgical silicon. The melted silicon is frozen in a directed manner. A crystallization front is formed during the directed freezing process, where the front has a shape of a sector of a spherical surface. The freezing process is performed in a processing furnace. The metallurgical silicon is obtained from a carbothermic reduction of silicon dioxides using plastics, where the carbothermic reduction is performed in a curved furnace.</p> |
