Method of processing materials suitable for producing high purity silicon

The present invention relates to a method of processing materials, especially at elevated temperatures in non-oxidizing atmosphere, such as using carbon-carbon composite materials for producing high purity silicon in the manufacture of solar modules. The method comprises the steps of supporting a sh...

Zusammenfassung:	The present invention relates to a method of processing materials, especially at elevated temperatures in non-oxidizing atmosphere, such as using carbon-carbon composite materials for producing high purity silicon in the manufacture of solar modules. The method comprises the steps of supporting a shaped support liner, nesting a crucible within the shaped support liner, elevating a temperature of the crucible and containing a molten feedstock within the crucible.
