Influence of sintering methods on microstructure and ionic conductivity of La1.95Sr0.05Zr2O6.975 synthesized by co-precipitation

“…Pyrochlore-based ceramics with the generic formula A 2 B 2 O 7 have become a very active field of research in the area of solid-state physics, chemistry, and engineering because of their wide variety of applications such as ionic conductors in fuel cells [1], immobilization of actinides materials in nuclear waste [2]- [3] and catalysis [4]. Mechanical and transport properties are strongly related to their microstructure, which in turn depends on the synthesis conditions.…”

Order–disorder transition in the Nd2−yYyZr2O7 system: Probed by X-ray diffraction and Raman spectroscopy

“…Pyrochlore-structured compositions have been attracting an ever-growing attention due to their wide range of properties such as ionic conductivity [1,2], superconductivity [3], luminescence [4], ferromagnetism [5] and catalysis [6], etc. Moreover, the zirconate pyrochlores are important ceramic waste forms for actinide immobilization and are among the principal host phases currently considered for the disposition of Pu from dismantled nuclear weapons and reactors [7].…”

Influence of CaO on structure and electrical conductivity of pyrochlore-type Sm2Zr2O7

“…These compounds can be used as candidates for catalysts [2,3], nuclear waste disposal [4,5] and thermal barrier coatings (TBCs) [6], due to their interesting physical and chemical properties. Especially, their electrical properties depending on the composition and the degree of disorder on the cation sites [7] make them promising hosts for solid electrolytes in high-temperature fuel cells.…”
