    摘要: A fine carbon fiber having an outer diameter of 1 to 80 nm and an aspect ratio of 10 to 30,000, comprising a hollow center portion and a multi-layer sheath structure of a plurality of carbon layers, the layers forming annular rings, wherein the sheath-forming carbon layers form an incomplete sheath, i.e., the carbon layers are partially broken or disrupted in a longitudinal direction, and the outer diameter of the carbon fiber and/or the diameter of the hollow center portion are not uniform in a longitudinal direction. The carbon fiber is obtained by instantaneously reacting a carrier gas at a high temperature and an organic compound gas kept at a temperature below the decomposition temperature of the transition metal compound and has a conductivity equivalent to that of a conventional vapor phase method and is useful as a filler material in resins, rubbers, paints and the like.

    摘要: In an expanded carbon fiber product according to the present invention, a number of hexagonal carbon layers in the shape of a cup having no bottom are stacked. At least part of edges of the hexagonal carbon layers is exposed at an outer surface or inner surface of the expanded carbon fiber product. At least part of gaps between the hexagonal carbon layers is larger than the gaps between the hexagonal carbon layers at the time of vapor growth.

    摘要: A graphite nanofiber material herein provided has a cylindrical structure in which graphene sheets each having an ice-cream cone-like shape whose tip is cut off are put in layers through catalytic metal particles; or a structure in which small pieces of graphene sheets having a shape adapted for the facial shape of a catalytic metal particle are put on top of each other through the catalytic metal particles. The catalytic metal comprises Fe, Co or an alloy including at least one of these metals. The material can be used for producing an electron-emitting source, a display element, which is designed in such a manner that only a desired portion of a luminous body emits light, a negative electrode carbonaceous material for batteries and a lithium ion secondary battery.

    摘要: The present invention relates to a a continuous process for producing carbon fibrils by decomposing a source of carbon at elevated temperatures in contact with a multivalent metal and recovering the fibrils formed thereby comprising the steps of introducing catalyst particles having a size of up to 400 µm (microns) and comprising at least one multivalent transition metal on a particulate substrate into a reactor heated to a temperature of 500°C to 1500°C, and recovering the fibrils formed thereby wherein said metal is present on said substrate as a multiplicity of discontinuous catalytic sites which, at least during fibril formation, have a size of 3,5 to 70 nm (35 to 700 Å) which size is measured by measuring the size of the transition metal particles recovered along with produced fibrils. This invention also relates to a reaction apparatus to be used for carrying out said process.
