Abstract

Graphite powder (57-74 μm) was fluorinated at 380°C for 1 h-2 weeks. The composition of the products ranged from CF_0.055 to CF_0.659. X-Ray diffractometry showed the formation of graphite fluoride, (C₂F)_n with a trace of C_χF phase with planar layers in addition to unreacted graphite which finally disappeared. Raman spectroscopy clearly revealed the existence of a fluorinated phase with planar layers with sp² structure.
