Abstract:

The chemistry of rare earths is fundamental to an understanding of the role of rare earths as corrosion inhibitors and to the preparation of effective rare earth-containing inhibitors. This chapter defines rare earth elements and their place in the Periodic Table, including electronic configurations, oxidation states and the lanthanoid contraction, their discovery, location and abundance, and their uses other than as corrosion inhibitors. A major section is devoted to the general chemistry of rare earths ...
