Insights into thermal reduction of the oxidized graphite ...

Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

Graphite Electrode - an overview | ScienceDirect Topics

Electrode consumption varies between 1.8 and 9.9 kg/t of liquid steel (Parkash, 2010) depending on the process characteristics and electrode quality. Ameling et al. (2011) reported that the electrode consumption in Germany in 2010 was approximately 1.1 kg per ton as a result of the reduction of time between the taps to 40 min and consequently the lower electricity …
