Silicon carbide whiskers (SiC( w )) are synthesized by the pyrolysis of rayon fibers impregnated with sol—gel‐derived SiO 2 . The influence of boric acid on whisker growth and the effect of varying the TEOS:rayon weight ratio are studied and reported. Evolution of SiC( w ) from impregnated rayon fibers in the carbonized and in the carbothermal stages is investigated.
