Abstract: Improved polycrystalline silicon manufacture is achieved by providing polycrystalline silicon rods, comminuting the polycrystalline silicon rods into polycrystalline silicon chunks, and packing the polycrystalline silicon chunks by introducing the polycrystalline silicon chunks into a solid and intrinsically stable container comprising a base, a wall and an opening, the container having the form of a truncated cone or truncated pyramid with two different-sized areas of base and opening and with a lateral surface, the base area being greater than the area of the opening of the container, the wall of the container having a thickness of at least 0.5 mm, and an angle between a lateral line and a vertical axis of cone or pyramid being at least 2°.
