Abstract

PURPOSE: To manufacture the titled pure silicon granules not polluted by impure metallic components by crushing polycrystalline silicon by means of rolls made of high purity silicon.
CONSTITUTION: Polycrystalline silicon fed from a feeder 1 as starting material is crushed by means of rolls 2, 2' made of high purity silicon and rotating in the arrow directions, and the crushed silicon is classified with sieves 4, 4' in a receiver 3 to collect pure silicon granules having the desired grain size, preferably about 0.1W1mm diameter. Said rolls 2, 2' may be formed by coating the surface of each metallic roll made of iron, stainless steel or the like with a high-purity silicon layer.
