Silicon Production - ScienceDirect

The chunks are melted at about 1420 °C to form a clear, viscous silicon melt. The polysilicon must melt congruently, not leaving any residue “floaters” on the surface of the melt, or any solid residues. Any moisture in the polysilicon may cause a violent reaction when heated and subsequent splashing of molten silicon.
