Abstract:
1. A method for producing a cluster of thin sheet graphite crystals composed of aggregates in such a state that thin sheet graphite crystals extend from the inside toward the outside, comprising: preparing a powdery and/or particulate material of an organic compound pre-baked to an extent of containing remaining hydrogen, charging the powdery and/or particulate material in a closed vessel made of a heat resistant material, and subjecting the powdery and/or particulate material together with the vessel to hot isostatic pressing treatment using a compressed gas atmosphere, wherein, a pre-baking temperature is 1000° C. or lower, a maximum temperature in the hot isostatic pressing treatment is 900° C. or more and lower than 2000° C., and the maximum temperature in the hot isostatic pressing treatment is higher than the pre-baking temperature, wherein a diameter or a width of the thin sheet graphite crystals is from 0.1 μm to 500 μm.
