The process according to the present invention involves mixing 100 parts by weight of a silica gel, containing 6.0 to 25.0% by weight with respect to a silicon of a water-soluble compound of at least one metal selected from the group consisting of iron, nickel and cobalt, with 110 to 400 parts by weight of furnace carbon black having a structure indicated by a DBP absorption number of 50 ml/100 g or higher, and then reacting the mixture under a non-oxidative atmosphere at a temperature of 1,300 DEG to 1,700 DEG C. to produce silicon carbide whiskers.
