Title:

CRUSHING METHOD OF POLYCRYSTAL SILICON

Document Type and Number:

Japanese Patent JP2015047594

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an efficient crushing method which allows mass production when mechanically crushing polycrystal silicon aggregating in tube.SOLUTION: By a primary crushing in which manual crushing is made with massive silicon, or, a combination of a primary crushing with a jaw crusher and a secondary crushing with a roll crusher, a high-purity polycrystal silicon is efficiently provided which has a particle size distribution suitable as a material of monocrystal silicon ingot or polycrystal silicon ingot for a silicon wafer for a semiconductor and a silicon wafer for a solar battery.
