Abstract
THIS volume contains a record of another of the valuable symposia held by the Faraday Society. The subject of the gases retained by solid metals bears on a number of technical processes, so that the papers contributed cover a wide range. Sir Robert Hadfield's introduction gives a useful summary of the knowledge of the gases in iron and steel, with a bibliography. The theoretical aspects are dealt with by Profs. Porter and McBain, the well-known case of the absorption of hydrogen by palladium receiving attention, whilst Dr. McCance's paper on balanced reactions in steel manufacture discusses the question of the equilibria in the steel furnace which determine the proportions of the various gases which will be in contact with the metal at the time of tapping. The view that the amorphous phase in solid metals is responsible for much of the dissolved gas is maintained by several of the contributors, but no evidence is adduced to prove that gases are insoluble in crystals of pure metals. The fact that the solubility of gases in molten metals increases with the temperature has often seemed remarkable, but Prof. Wilsmore points out that this is probably the normal behaviour, water being exceptional in its diminished solvent power for gases with increasing temperature. The discussion contains much that is of interest both to metallurgists and to physical chemists.
