The isotherm of bromine on pyrolytic graphite was studied at 20ยฐC by stepwise bromination, and several phases of graphite bromide were identified, which have compositions of C,Br, C,\*Br, C16Br and C,,,Br. X-ray studies show that these possess the socalled 2nd, 3rd, 4th and 5th stage structures resp
The in-plane superlattice and the twinned domain structure were found by single crystal X-ray diffraction to be preserved after exfoliation and collapse, though the graphite planes were slightly bent. The fractional expansion due to exfoliation was comparable for single crystals and HOPG. The degree
Electrical conductivity, transverse magnetoresistance, and Hall coefficient, both of graphite in the course of bromination and of potassium-graphite intercalation compounds (K-GICs) in the course of ammoniation, were determined. Concentrations and mobilities of holes and electrons (q,, it,, p+, kc)
