Abstract
PURPOSE: To directly manufacture high-grade carbonaceous whiskers from a vapor phase in a high yield by contacting a catalyst practically in a finely dispersed state to a hydrocarbon gas under an oxidizing atmosphere in a predetermined temp. range.
CONSTITUTION: Under an oxidizing atmosphere a known catalyst such as Fe, Co, transistion metal or a compound thereof practically in a finely dispersed state is contacted to a hydrocarbon gas such as methane at 900W1,600°C to manufacture carbonaceous whishkers. To form the oxidizing atmosphere CO2 gas acting as an oxidizing gas especially at high temp. is preferably used, and the atmosphere is adjusted to 0.05W5l as CO2 gas to 1l of the starting material gas. As a result, whiskers are formed very efficiently, and the practical number of whiskers formed is 10W100 times as many as that of whiskers foemed by a conventinal method.
