BROMINE EXCHANGE IN GRAPHITE-BROMINE LAMELLAR COMPOUNDS
Technical Report
·
OSTI ID:4652945
A kinetic study of the exchange of normal and radioactive bromine in graphite-bromine lamellar compounds was made at temperatures of 30 to 50 deg C. Natural and synthetic graphite powders were investigated. Two alternative mechanisms for the exchange, volume diffusion and surface exchange, were considered. The data are in better agreement with the diffusion mechanism. Diffusion coefficients of 10/sup -9/ to 10/sup -8/ cm/sup 2//sec and an activation energy of 11 to 14 kcal/mole were calculated for the natural graphite powders. The diffusion coefficients increased with increasing bromine content. Reversibly absorbed bromine exchanged more rapidly than irreversibly absorbed bromine. (auth)
