Title:
METHOD FOR REMOVING SILICON POWDER IN COOLANT FOR MONOCRYSTALLINE SILICON SLICING WITH DIAMOND WIRE
Document Type and Number:
WIPO Patent Application WO/2024/060845
Kind Code:
A1
Abstract:
A method for removing silicon powder in a coolant for monocrystalline silicon slicing with a diamond wire, including following steps: preparing an inorganic coagulation-inducing saline solution; mixing the inorganic coagulation-inducing saline solution with a waste coolant of the coolant after monocrystalline silicon slicing to obtain a mixture, and leaving the mixture to stand to carry out agglomeration and precipitation of the silicon powder. The inorganic coagulation-inducing saline solution has advantages of being inexpensive, non-toxic, easy to obtain, and achieving good agglomeration and precipitation.
