The present work focuses on two fluorite-structured groups of materials: the hydrides of the rare earths (and actinides) and several specific metal oxides, and is authored by researchers among the most competent and active in the field. By contrast to the classical “historic” alkaline-earth halides, non-stoichiometry appears as a key issue for both groups treated here. The former group has attracted particularly close attention because of its possible candidature as hydrogen storage material within the vast prospect of the clean energy economy.

In the second group, a chapter is devoted to the (antifluorite-type) lithium oxide, a candidate for (super)ionic batteries (again interesting for the clean energy technology) and as a tritium “breeder” in fusion reactor walls. Finally, two more chapters are dedicated to the radiation effects on actinide dioxides (like uranium dioxide), and yttria-stabilized zirconium dioxide which is envisioned as an inert confinement matrix for actinide transmutation in nuclear reactors.

“Calcium fluoride, CaF2, occurs naturally as the mineral fluorite which lends its name to the deceptively simple cubic structure of four FCC Ca atoms and eight tetrahedrally coordinated F atoms. In simplicity often lies rich diversity, this is certainly the case with materials with the fluorite structure. The book “Properties of Fluorite Structure Materials” Edited by Peter Vajda and Jean-Marc Costantini demonstrates how such diversity in fluorite materials arrives from small changes in stoichiometry.” READ MORE…Dr. Clark S.
