The isotherm of bromine on pyrolytic graphite was studied at 20Β°C 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

β¦ Synopsis
Crystal structure, electric conductivity and thermal stability of graphite-CrO,Cl, lamellar compound were investigated. X-ray diffraction studies of C,,.,CrO,Cl, show that it possesses a 3rd stage lamellar structure with I, of 14.87 A. This lamellar compound is unusually stable and its electric conductivity, as well as its composition, show only a slight change after complete evacuation of reacting CrO&l, gas. When heattreated in a vacuum, its electric conductivity shows a considerable decrease, whereas its composition changes very slowly up to 300Β°C.
