From the PublisherOverall, this volume is an excellent addition to the series.
RIC News, Vol. XXXVI, No. 1
Chapter 98 adds significantly to an evaluation of systematic, experimental low-temperature studies of the ambivalent behaviours of cerium (ferromagnetism, antiferromagnetism, spin glass, superconductivity etc.) which depend upon its environment in materials. The conclusions arrived at should provide new data against which the theory can be advanced.
The next chapter provides a review of rare earth carbides, emphasizing the thermodynamics, phase diagrams, crystal structures and physical properties. The binary rare earth carbides present an exceptionally wide range of compositions and structures both as solids and gas-phase molecules. Complex carbides with additional metal and non-metal components also receive attention.
Metal-rich halides (i.e. compounds with an X/R ratio <2) are the subject of the next chapter. The compounds are classified according to their structure and chemical bonding characteristics and their electrical and magnetic properties are also reviewed.
Chapter 101 deals with the preparation, structure, chemical and physical properties of heavy-metal fluoride glasses. Large amounts of rare earths can be added into these, and they possess a great potential for optical applications in the mid-infrared range as fiber optic glasses for communication and transmission of information, optical wave guides, fiber lasers and sensors.
The following chapter explores the chemical kinetics of solvent and ligand exchange in aqueous lanthanide solutions. A wealth of tabulated information on rate and equilibrium constants is provided in textual and tabular form. Chapter 103 considers the fundamentally important reactions of the lanthanide ions with water. These interactions are discussed for both solids and solutions. The hydrated species are considered in detail for the aqueous solution, revealing the consequences of the lanthanide series sequence.
The concluding chapter reviews macrocyclic complexes formed by rare earth and dioxouranium ions as templates. Synthetic trends and reactivity are considered as well as potential uses of these intriguing wrap-around structures.
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
