"Heterogeneous Equilibrium, alone, is an extensive study in itself and no discussion of it will be given here. It is known from this study that different phases are formed in various systems, the system consisting of two or more components. Some systems form an eutectic, which is a mixture of two solids which combine to form a liquid at a lower degree of temperature than either of the milting points of the two solids, as shown in the two component system of KCl and LiCl¹; some systems form solid solutions in which there is no eutectic formed, and the solids deposit in no definite proportions, as in the two component system of Cu and Ni¹. There are many systems in which more complicated conditions occur, however, the most widely known system is that one which forms an "eutectic"." – Introduction, Page 1.
