    Abstract: PURPOSE: A porosity nano silicon carbide and a manufacturing method thereof are provided to simplify processing conditions and prevent cracks. CONSTITUTION: A porosity nano silicon carbide manufacturing method includes next steps. A polymer precursor and silicone compound are mixed with solvent. The compound which is obtained in the stage is electro-spined in a sphere or fiber form. A heat-treatment process is executed for the electrospinning result. The polymer precursor is selected among petroleum pitch, coal type pitch, polyimide, polybenzimidazole, poly acrylonitrile, polyaramide, polyaniline, mesophase pitch, furfuryl alcohol, phenol, cellulose, sucrose, polyvinylchloride and their mixture.
