This volume of the Handbook illustrates the rich variety of topics covered by rare earth science. Three chapters are devoted to the description of solid state compounds: skutterudites (Chapter 211), rare earth -antimony systems (Chapter 212), and rare earth-manganese perovskites (Chapter 214). Two other reviews deal with solid state properties: one contribution includes information on existing thermodynamic data of lanthanide trihalides (Chapter 213) while the other one describes optical properties of rare earth compounds under pressure (Chapter 217). Finally, two chapters focus on solution chemistry. The state of the art in unraveling solution structure of lanthanide-containing coordination compounds by paramagnetic nuclear magnetic resonance is outlined in Chapter 215. The potential of time-resolved, laser-induced emission spectroscopy for the analysis of lanthanide and actinide solutions is presented and critically discussed in Chapter 216.
This was the last volume in this distinguished series of handbooks published in the twentieth century. It contains three chapters dealing with rare earth alloys and intermetallic compounds.
Chapter one deals with ternary rare earth-germanium alloys, their phase diagrams and the crystal structures of the intermediate phases. In particular the group VIII metals are discussed, of which the first member of each row (iron, ruthenium and osmium) forms only half the number of compounds as the other two members, cobalt and nickel and their congeners. The author also observes that the ternary alloy systems of the rare earths and germanium with the s and p elements have hardly been investigated. The chapter ends with a discussion on the general trends and unusual features observed in the various sets of ternary phase diagrams.
Chapters two describes in detail the various structure types that have been adopted by the rare earth-germanium ternary intermetallic compounds. The correlations, crystal chemistry and interrelationships of the 135 structure types are discussed. This paper also reviews quaternary compounds and superstructures.
The final chapter deals with scandium alloys and intermetallic compounds, binary, ternary and higher order systems. The authors summarize the various phase diagrams of scandium systems and present the crystal structure properties of the various intermediate phases. The chapter finishes with a presentation of physical property data on scandium intermetallic phases. The results are divided into three groups - compounds which have a magnetic ground state, a superconducting ground state and those with neither a magnetic or a superconducting ground state
