ABSTRACT:
The present invention is directed to silicon carbide whisker recovery from a mixture of silicon carbide whiskers and carbonaceous silicon carbide particles. The invention involves shredding the mixture down to a specified size, dispersing the mixture in water to form an aqueous mixture, mixing in an effective amount of flocculating agent, agitating the aqueous mixture, mixing the aqueous mixture with an immiscible organic liquid, agitating the resulting water-organic liquid mixture, allowing settling of the aqueous mixture and organic liquid so as to establish two liquid phases, separating the two liquid phases into an organic liquid phase and an aqueous phase and, lastly, performing a solid-liquid separation on the aqueous phase, thereby obtaining from the aqueous phase the desired silicon carbide whiskers.
