About This Book
A clear, non-mathematical exposition of the phase rule that defines phases, components, and degrees of freedom and derives the rule for classifying chemical equilibria. The text analyzes typical one- and multi-component systems, interprets phase diagrams and cooling curves, and outlines methods for determining the composition of solid phases without direct analysis. Worked examples include vapor–liquid equilibria, iron–carbon alloys, reciprocal salt pairs, and processes relevant to the ammonia–soda and blast-furnace systems. Emphasis is placed on practical applications to metallurgy, geology, and industrial chemistry and on using experimental observations to guide equilibrium investigations.
