PROCESS FOR THE PRODUCTION AND TREATMENT OF GRAPHITE POWDERS

摘要

The invention relates to processes for the production and thermal treatment of carbon material, in particular graphite powders, in an Acheson type oven, using a functional filler comprised essentially of graphitic material in particulate form allowing electrical current to flow through the charge. The particulate form of the filler allows greater flexibility and can be used to control the degree of direct and indirect heating, resulting in more uniform products compared to the prior art. Such graphite materials are typically employed as an additive in polymers, batteries or other applications.
