Graphite burning temperature
WebA mixture of two carbonaceous materials, graphite and carbon black, are thermally oxidized in either i) outside total diffusion-limited regime or ii) total diffusion-limited regime. Depending on the treatment applied it is possible to purify either graphite, a trivial task, or carbon black, a task thought impossible. WebGraphite nanofibers (GNF) are a newly developed type of material that are produced by the interaction of selected metal particles with carbon-containing gases at temperatures in excess of 500 °C.
