ABSTRACT:
A process of preparing carbon fibers in a floating state by reacting a mixed gas consisted of a gas of organic metal compound or compounds, a carrier gas and desirably a gas of carbon compound or compounds at the elevated temperature of 600.degree. to 1300.degree. C. is disclosed, in which the fine carbon fibers having a diameter of 0.05 to 2 .mu.m, a length of 2 to 3000 .mu.m and an aspect ratio of 2 to 30,000 as well as a high degree of preferred orientation of carbon layers may be produced in a high yield and a high productivity.
