Abstract
Reduction of contamination and the proportion of fines fractions in the packaging of rod form polysilicon is achieved by directly filling a plastic bag with polysilicon from a cleaning bowl by a rotating motion which causes polysilicon chunks to slide into the bag.
Claims16
A polysilicon containing package, comprising a corrugated fiberboard container having an n-gonal cross section, wherein n=8 to 16, comprising a bottom, n=8 to 16 side walls, and a removable lid for closing the container, a double bag of plastic installed in the container having an interior comprising polysilicon, wherein polysilicon is positioned within the double bag of plastic in such a way that cylindrical and/or semicylindrical rod pieces made of polysilicon are arranged within the double bag adjacent the bottom and inner walls of the container, and the rod pieces so arranged surround polysilicon in the form of chunks.
