This classic work has now been completely revised and updated and much new material has been added to take account of new developments in the field. The 5th Edition includes an extended treatment of the thermodynamics of metallic solutions; many new recently devised experimental methods; novel modes of estimating unknown and testing known thermochemical values, coupled with improved practical examples of thermochemical treatment of metallurgical problems with industrial and other practical applications. The thermochemical data tables (150 pp) have been completely updated and the extensive bibliography of over 1400 references covers the literature up to 1975. Hence this comprehensive survey will prove of continuing value to a wide range of disciplines and of particular use to senior students of metallurgy, materials science, physical chemistry and chemical engineering
