Abstract

This chapter evolves out of many years of research in materials for thermoelectrics. The study of phase ­diagrams is necessary to understand the synthesis of established thermoelectric materials, enhance the material properties, and contribute to the development of new and better materials. During the last century, the development of such materials was made with the help of experimental phase diagrams. This approach was not so bad; in fact, the materials were based on few well-known systems. Now, with the development of new materials such as the intermetallics, this thermodynamic approach is necessary for tailoring such materials; also, they are multicomponent (e.g., some skutterudites contain more then five elements).
