Abstract
SiC anti-oxidation coatings on polyacrylonitrile (PAN) based carbon felt fibers were prepared through sintering a pre-immersed felt in a vacuum. The crucial act here was to add egg white into the immersion liquid. Scanning electron microscope (SEM), energy dispersive X-ray (EDX) and differential scanning calorimetry-thermogravimetric (DSC-TGA) analyses for the coated felt fibers as well as for another a uncoated sample were made to basically study the coating effects. The egg white liquid acts both as a favorable natural agglomerant and an as active carbon source during the sintering; this leads to an excellent coating.

Keywords: Egg white, SiC, Coating.
