POLYCRYSTALLINE SILICON FRAGMENT, METHOD FOR MANUFACTURING POLYCRYSTALLINE SILICON FRAGMENT, AND POLYCRYSTALLINE SILICON BLOCK FRACTURE DEVICE

摘要

[Problem] To provide polycrystalline silicon fragments that can contribute to improvement of operability and productivity in manufacture of single crystal silicon ingots. [Solution] Polycrystalline silicon fragments obtained by fracturing polycrystalline silicon blocks, the content ratio of polycrystalline silicon powder having a particle size of 500 to 1000 μm being 0.1 to 40 ppmw.
