    摘要： A method for mechanically classifying polycrystalline silicon chunks or granules with a vibratory screening machine, involves setting silicon chunks or granules present on one or more screens each comprising a screen lining in vibration such that the silicon chunks or silicon granules perform a movement which causes the silicon chunks or silicon granules to be separated into various size classes, wherein a screening index is greater than or equal to 0.6 and less than or equal to 9.0.

    摘要： An apparatus is disclosed for comminuting a polycrystalline silicon rod, which apparatus includes a base, at least one movable comminuting tool and optionally at least one immovable anvil. A silicon rod to be comminuted lies on a longitudinal axis oriented parallel or virtually parallel to the surface of the base and can be adjusted between the comminuting tool and anvil. Also disclosed is a method for comminuting a polycrystalline silicon rod.

    摘要： The invention relates to a polycrystalline silicon portion having at least one fracture surface or cut surface, which includes metal contamination of from 0.07 ng/cm2 to 1 ng/cm2. The invention also relates to a method for breaking a silicon body, preferably a rod of polycrystalline silicon, including the steps: a) determining the lowest natural bending frequency of the silicon body; b) exciting the silicon body in its lowest natural bending frequency by means of an oscillation generator, the excitation being carried out at an excitation point of the silicon body such that the silicon body breaks at the excitation point; so that a silicon portion having a fracture surface results which includes metal contamination of from 0.07 ng/cm2 to 1 ng/cm2.
