The Formation of graphite/bromine II. The Influence of external presure on bromine uptake

Abstract

Experiments are described in which plates of well-ordered graphite were subjected to pressures of up to 300 atm while in contact with liquid bromine or with its solutions in carbon tetrachloride. Measurements were made of limiting uptake at 20 and at 50 °C. Effects of external pressure in reducing bromine uptake are discussed in relation to internal hindrances to crystal compound formation. It is estimated that, very roughly, internal constraints correspond to an external applied pressure between 100 and 300 atm.
