PROCESS FOR PRODUCING EXFOLIATED GRAPHITE PARTICLES

摘要

1. Process for the preparation of expanded graphite particles in which graphite intercalation compounds are formed by the action of a gaseous oxidising agent on graphite particles which have a high degree of ordering and said compounds are decomposed by heating, characterised in that the graphite particles are moved through a reactor containing oxidising agents from the group SO3 , NO2 , N2 O4 , N2 O5 and the graphite intercalation compound formed is removed from the reactor continuously or stepwise.
