The structural transformation occurring to a mixture of cubic CeO2 and monoclinic ZrO2 by High-energy Mechanical Milling (MM) has Been followed by neutron diffraction. Rietveld analysis indicate that 9 hours of milling produce a tetragonal solid solution for Zr-rich composition and a nanocrystalline cubic solid solution for Ce-P ich composition.

Abstract
The structural transformation occurring to a mixture of cubic CeO2 and monoclinic ZrO2 by High-energy Mechanical Milling (MM) has Been followed by neutron diffraction. Rietveld analysis indicate that 9 hours of milling produce a tetragonal solid solution for Zr-rich composition and a nanocrystalline cubic solid solution for Ce-P ich composition.File in questo prodotto:
