Executive - International Graphite

The value-added processing of graphite is one of our key strengths at AETC. We believe that value-add beneficiation cannot be efficiently performed at the mining or primary processing sites. The ability of a successful graphite producer to perform secondary (e.g. value-added) processing should be complemented by its ability to operate ...

Graphite | Earth Sciences Museum | University of Waterloo

Primary synthetic graphite is obtained by transformation of carbonaceous precursor into graphite through an industrial process, called graphitisation (temperature >3000°C). Graphitisation is a microstructural change which can occur in carbon or low alloy steels that are exposed to elevated temperatures, between approximately 425°C and 600°C ...
