ABSTRACT:
A method for the disintegration of silicon for preparation of semiconductor materials. Polycrystalline silicon in a rod form is subjected to microwave radiation in an oven for a short period of time, whereby the rod-like polycrystalline silicon is dielectrically heated quickly from its inside thereby causing it to be disintegrated.
