Title:
METHOD FOR SEPARATING SILICON AND CARBON PART FOR PRODUCING POLYCRYSTALLINE SILICON
Document Type and Number:
WIPO Patent Application WO/2016/178454
Kind Code:
A1
Abstract:
Disclosed is a method for separating silicon and a carbon part for producing polycrystalline silicon, whereby it is possible to substantially improve regeneration and productivity of the carbon part, and it is possible to maximise the recycling rate of polycrystalline silicon attached to the carbon part. The method for separating silicon and a carbon part for producing polycrystalline silicon may comprise: a silicon coating step in which polycrystalline silicon attached to the carbon part is removed by being cut to a predetermined thickness, within a range such that physical damage is not imparted to the carbon part; a silicon separation step in which the carbon part and residual polycrystalline silicon attached to the carbon part are separated by making a silicon-separation solution penetrate between the contacting surfaces of the polycrystalline silicon and the carbon part; and a carbon-part washing step in which the carbon part, from which the polycrystalline silicon has been separated, is repeatedly washed using water in order to remove silicon-separation solution absorbed by the carbon part.
