Synthesis and sintering of ceramic nanocomposites with high mixed conductivity [PDF]

open access: yesScience of Sintering, 2005
Metastable solid solutions of complex oxides with fluorite and perovskite structures are obtained by mechanosynthesis. Dense ceramics on the base of these metastable phases was obtained by thermal sintering of nanopowders due to kinetic stabilization ...

Dipolar glass state in BaCe0.3Ti0.7O3 perovskite solid solutions

open access: yesJournal of Alloys and Compounds, 2021
An extensive broadband dielectric spectroscopy study of BaCe0.3Ti0.7O3 ceramics is presented. The distribution of relaxation times of the system derived from the frequency dependence of complex dielectric permittivity are similar to the ones observed in dipolar glasses.
