Nanostructured pyrochlore reveals unexpected order

Oxide materials such as pyrochlores are used in nuclear waste immobilization matrices and fuel cells. A team of researchers at the French Alternative Energies and Atomic Energy Commission (CEA) and the National Center for Scientific Research (CNRS), together with colleagues in Australia and Japan, have now studied the atomic composition of the text-book pyrochlore La2Zr2O7 to better understand these materials. The pyrochlore, which is considered to be a defect fluorite, is the result of intricate disorder at the atomic scale thanks to randomly distributed and fully-ordered nano-domains…..
