Carbon Graphites | Schunk Carbon Technology
We speak of carbon graphites when the bodies are temperature treated at a temperature below 1200°C, i.e. carbonized. After carbonization, there is still no continuous graphite structure; the bodies are of high strength and hardness. For many applications, however, such carbon materials already have the desired properties.

Helical microtubules of graphitic carbon | Nature
On 7 November 1991, Sumio Iijima announced in Nature the preparation of nanometre-size, needle-like tubes of carbon — now familiar as 'nanotubes'. Used in …
Low‐temperature synthesis of graphitic carbon‐coated …
Comparing to the CV curve of Si@GC42, with lower content of graphitic carbon coating, the graphite lithiation-delithiation behavior in Si@GC30 diminishes; Instead, the CV peaks of Si lithiation-delithiation become more pronounced. When the carbon content is further reduced, the cycle stability of Si@GC21 decreases, which indicates Si@GC21 does ...

Electromagnetic interference shielding effectiveness of …
Abstract. Carbon materials for electromagnetic interference (EMI) shielding are reviewed. They include composite materials, colloidal graphite and flexible graphite. Carbon filaments of submicron diameter are effective for use in composite materials, especially after electroplating with nickel. Flexible graphite is attractive for EMI gaskets.
Lithium Diffusion in Graphitic Carbon | The Journal of …
Graphitic carbon is currently considered the state-of-the-art material for the negative electrode in lithium ion cells, mainly due to its high reversibility and low operating potential. However, carbon anodes exhibit mediocre charge/discharge rate performance, which contributes to severe transport-induced surface structural damage upon prolonged …
Preparation of high-crystallinity synthetic graphite from …
The graphite layer of hard carbon has a short length and a complicated orientation, so hard carbon is difficult to prepare as high-crystallinity synthetic graphite even with graphitization (over 2400 °C) [9,10,11,12]. If high-crystallinity synthetic graphite could be prepared from hard carbon, it would be possible to solve the issue of the ...
