Definitions

• the invention relates to the packaging of polysilicon.
• Polycrystalline silicon or polysilicon in short can be deposited by means of the Siemens method from chlorosilanes in rod form. Subsequently, the rod-shaped polysilicon is usually broken as free of contamination as possible fragments or polysilicon fracture. Such a method as well as a

• cuboid boxes are used. These boxes are adapted to the size of the packaging bag or to the amount and dimensions of the polycrystalline silicon to be packaged.
• Reinforcing structure or a shape-forming element is needed.
• separating elements or cuboid boxes are required in the large packaging. This makes this type of packaging consuming.
• WO 2015/007490 A1 discloses a transport container containing at least two plastic bags, in each of which polycrystalline silicon fragments are, characterized by a packing density of greater than or equal to 500 kg / m 3 or greater than 800 kg / m 3 .
• the packing density is defined as the weight of the weight of polycrystalline silicon fragments in relation to the internal volume of the transport container.
• Vibrations and vibrations during transport are all the more harmful the more freedom a packaged polysilicon bag has in a secondary one
• Packing unit such as has a carton. Too narrow a packaging leads to an increase in piercings, too loose packaging can also lead to piercings and significantly more fines.
• mold-forming elements made of PU, polyester or expandable polystyrene or another plastic are additionally introduced, as also described in US 2013269295 A1.
• plastic bags are used for the packaging of polysilicon, which are then assembled into larger packaging containers.
• the effort and cost of making this packaging are high.
• the disadvantage is that smaller individual packages offer little or no space for larger fragments and bars.
• Plastic is used, wherein in the double bag polysilicon is filled.
• double bag is to be understood that two bags of plastic, preferably made of PE, are inserted into the container, with one bag is placed in the other bag (inner and outer bags).
• it may be a prefabricated bag, which is made of two plastic films
• the polysilicon to be packaged comes from comminuted polysilicon rods and preferably comprises fragments of different sizes.
• the polysilicon preferably comprises rod pieces in the form of solid or semi-cylinders.
• the packing density that is to say the weight of the weight of polysilicon with respect to the internal volume of the container, is preferably 900-1300 kg / m 3 and more preferably 1000-1 100 kg / m 3 .

• a height of the container of 400 to 600 mm has proven to be particularly ergonomic. This allows the bottom of the container during manual loading and unloading
• the packaged polysilicon comprises debris and rod pieces in the form of solid or semi-cylinders.
• debris and rod pieces in the form of solid or semi-cylinders are packaged such that the round sides of half cylinder bar pieces and the solid cylinder bar pieces (stub pieces) rest on the inside of the container. Between the lying on the inside of the container bar pieces and the inside or inside wall is no polysilicon, no fragments. The rod pieces can touch the inner wall of the container with its round side.
• Polysilicon may be arranged in the form of fragments or rod pieces or both, between the rod pieces lying on the inner walls of the container.
• This embodiment provides a maximum level of puncture resistance and at the same time avoids relative movements of the fragments.
• the semi- and fully cylindrical rod pieces surrounding the fragments ensure a strong fixation of the internal fragments, so that the relative movements between fragments are contained and thus the formation of fines is counteracted by impact comminution of the fragments.
• a double plastic bag with a film thickness of 100 to 200 ⁇ is inserted into the container. It has been found that this represents an optimized solution, taking into account the packaging costs in terms of puncture resistance and handling.
