Abstract
The present invention relates to an apparatus and method for purifying materials using a fractional solidification. Devices and methods shown provide control over a temperature gradient and cooling rate during fractional solidification, which results in a material of higher purity. The apparatus and methods of the present invention can be used to make silicon material for use in solar applications such as solar cells.
