Synthesis of silicon carbide through the sol-gel process from rayon fibers
Silicon carbide whiskers (SiC(w)) are synthesized by the pyrolysis of rayon fibers impregnated with sol-gel-derived SiO2, 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.
