Abstract
OF DISCLOSURE To provide a novel method for producing a polycrystalline silicon processed article, the method including a step for preventing carbon contamination of a polycrystalline silicon rod surface by a carbon member present on the polycrystalline silicon rod end portion when handling a polycrystalline silicon rod obtained by the Siemens method. Provided is a method for producing a polycrystalline silicon processed article, the method being characterized in that, in a method for removing a polycrystalline silicon rod obtained by precipitating polycrystalline silicon on a silicon core wire held by a carbon member connected to an electrode in a reactor by the Siemens method in a state in which the carbon member is included at the end portion thereof and processing the polycrystalline silicon rod, there is included a step for detaching the polycrystalline silicon rod from the electrode and covering the carbon member present on the end portion of the polycrystalline silicon rod using a covering material until processing, whereby the polycrystalline silicon rod and the carbon member are handled in a separated state.
