Silicon carbide whiskers (SiC(w)) are synthesized by the pyrolysis of rayon fibres impregnated with sol-gel-derived Si02. The influence of boric acid on whisker growth and the effect of varying TEOS:rayon weight ratio are studied and reported. Evolution of SiC(w) from impregnated rayon fibres in the carbonized and in the carbothermal stages is investigated.
