    Abstract: Polycrystalline silicon chunks are packed for further processing and/or for shipment with minimal contamination by introducing the chunks into a cardboard container lined with a non-contaminating plastic. The process is economical, avoids the problems associated with packaging in plastic bags, and provides far less contamination and spillage during transport.

    Abstract: The invention relates to a process for packaging polycrystalline silicon in the form of chunks, including the following steps: (a) providing polycrystalline silicon in a metering system; (b) filling polycrystalline silicon from the metering system, which removes fines by use of screening, into a plastic bag arranged below the metering system. The weight of the plastic bag with the polycrystalline silicon introduced is determined during the filling step and the filling step is ended after the attainment of a target weight. A fall height of the polycrystalline silicon from the metering system into the plastic bag is kept at less than 450 mm by use of at least one clamp apparatus over the entire filling step.

    Abstract: Polycrystalline silicon in the form of chunks packed in plastic bags containing a mass of at least 5 kg, including chunks of size from 20 to 200 mm, wherein any fines fraction in the plastic bag is less than 900 ppmw, preferably less than 300 ppmw, more preferably less than 10 ppmw. The polycrystalline silicon, after comminution of a silicon rod obtained by CVD (Siemens process), is sorted and classified, optionally dedusted and then metered and packed. Metering and packing units include elements for removing fines or small particles during metering and during packing. The packing unit includes an energy absorber or a reservoir vessel which enables sliding or slipping of the silicon chunks into the plastic bag. Gas flow generated within the plastic bag after the bag has been filled transports the dust or small particles out of the bag, and these are sucked out with a suction device.

    Abstract: Polycrystalline silicon is produced by depositing polycrystalline silicon onto U-shaped slim rods, deinstalling at least one polycrystalline silicon rod pair from the reactor, removing graphite residues from the electrode-side ends of the polycrystalline silicon rods of the polycrystalline silicon rod pair, and comminuting the polycrystalline silicon rods into rod pieces or into chunks, wherein prior to deinstallation of the polycrystalline silicon rod pairs from the reactor, the polycrystalline silicon rod pairs are at least partially with a plastics material bag made of a plastics material film having a thickness of more than 150 μm, wherein the plastics material bag comprises weights at its opening. The invention further relates to a polycrystalline silicon rod pair which has a rod diameter of 190 mm or more and is covered by a plastics material bag made of a plastics material film having a thickness of more than 150 μm.
