The activation reactions of organic substrates involving tantalum compounds and complexes as compared with other transition metals have a relatively recent history, and therefore they are by far the least studied. The first chapter presents research data published by the authors in the last five years, on the use of catalysts based on tantalum compounds and complexes. In Chapter 2, a systematic study has been undertaken of basic thermodynamic functions of tantalum through the whole range of its solid state. These functions include molar heat capacity, volume coefficient of thermal expansion, bulk modulus and molar volume. In the last chapter, the findings from electron-microscopic studies of copper-tantalum welded joints that do not possess mutual solubility are examined. Joints with both flat and wavy interface are included. Findings from the study of other metal-metal and metal-intermetallic joints that were obtained by the authors were used for comparison.

Rare Earth Elements (REE) as well as tantalum and niobium are of tremendous importance because of their specific high-technology applications. The contributions gathered in this volume give an up-to-date survey on the mineralogy, primary ore deposits, prospecting, processing and applications of REE, Ta, and Nd, making this volume a useful handbook for practitioners and students. Finally, the comprehensive coverage of the fundamental aspects, especially as regards REE as tracers of geological phenomena, will prove extremely helpful.

Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.
