Hydrocarbons such as naphthalene and propylene can be used as the source gas. pimt the temperature of oil bath 1,
The raw material gas 2 is vaporized and mixed with an inert carrier gas of H, I N, I Aril, and the partial pressure of the raw material gas is adjusted to O.
Adjust to a range of i-500 wstHf. The mixed gas thus obtained was 1100 - 10t}Omlm
K kept electric F3K leads. A flat or cylindrical substrate made of a carbon material containing volatile hydrogen sulfide (Fig. 2 A (5) and "(S')) is placed inside the electric furnace, and the raw material gas is decomposed. The carbon atoms generated in this process form rutted vertical elements in the form of dense growth on the substrate.At this time, due to the interaction between the hydrocarbon gas evaporated from the substrate and the l# element generated by the decomposition of the raw material gas, It is presumed that the unique form of the present invention is formed.When the temperature of the electric furnace is changed, there is no essential change in the shape of the circumferential part, but the shape of the core part changes as shown below. There is a change in the temperature of the electric furnace.
When 1300 U is used, a core shaped like a stack of flat truncated conical containers is obtained, and 1300~zoost:
: When this is done, a core shaped like a stack of elongated truncated conical containers is obtained. The core is cylindrical and the diameter of the 1f diameter is SG-
It is 300X. ζThe resulting fibrous blue-like recombinant material is 200
By processing at a temperature higher than the manufacturing temperature in the range of 0 to ssoo<0>C, it is possible to obtain a fibrous ##-shaped lead carrier in which microcrystals have grown. In the present invention, the fibrous legophore includes fibrous graphite in which such microcrystals have grown.
