SILICON CARBIDE HOLLOW FIBER AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: A method for fabricating silicon carbide hollow fibers are provided to prepare silicon carbide hollow fibers using a sintering material capable of silicon carbide sintering at a low temperature compared with the case of spinning a conventional organosilazane polymer and performing heat treatment. CONSTITUTION: A method for fabricating silicon carbide hollow fibers comprises the steps of: (S210) preparing a composition including silicon carbide, sintering aids, polymers, dispersing agents and organic solvents; (S220) wet-spinning the composition using a spinneret; (S230) washing and drying the resultant to form high-polymer silicon carbide hollow fibers; and (S240) sintering polymer-silicon carbide hollow fibers to form silicon carbide hollow fibers.
