ABSTRACT:
Disclosed is a method of casting silicon metal. Silicon metal expands upon solidification. According to the disclosed method a void volume of from 1 to 10 percent of the silicon metal, basis molten silicon metal, is established within the molten silicon metal. The void volume is capable of being decreased in volume upon the solidification of the silicon metal. In this way, the increase in volume of the silicon metal upon solidification is offset.
