METHOD AND APPARATUS FOR CRUSHING SILICON ROD AND METHOD FOR PRODUCING SILICON LUMP

摘要

To provide a method and an apparatus for crushing a silicon rod capable of increasing a yield of a silicon lump with an appropriate size, and a method for producing a silicon lump.SOLUTION: In the method for crushing the silicon rod according to the present invention that crushes a silicon rod 2 by applying a high-voltage pulse discharge, the silicon rod 2 is crushed by moving an application position of the high-voltage pulse discharge to the silicon rod 2 relatively along a longitudinal direction of the silicon rod 2 while the silicon rod 2 is rotated. The silicon rod 2 is placed on, for example, a loop-shaped endless sheet 22, and the endless sheet 22 is rotated to rotate the silicon rod 2.SELECTED DRAWING: Figure 1
