High-permittivity and low-loss dielectric tunable pyrochlore thin films deposited by radio frequency magnetron sputtering from a lead zinc niobate target

Local Structure and Phase Formation of Lead Zinc Niobate Powders by X-Ray Absorption Spectroscopy

“…Pb 2 (Zn,Nb)O 7 is a rhombohedral pyrochlore that is also sometimes present. The pyrochlore phase is undesirable because of its relatively low dielectric constant and non-piezoelectric nature but have high-permittivity and low-loss dielectric tunable which are suitable for microwave dielectric applications [5].…”

Synthesis and Characterization of Pyrochlore Lead Zinc Niobate Nanopowders Derived from Zn₃Nb₂O₈ Precursor

“…There has been a great deal of interest in the preparation of single-phase pyrochlore powders as well as in the sintering and dielectric properties of cubic pyrochlore ceramics due to their high permittivity, low loss and low sintering temperature [9,10]. However, the complex chemical compositions and structures of these materials frustrated the early attempts to utilize these candidate low-firing dielectrics in practical applications especially for tunable capacitors [11]. Interestingly, no systematic study on the preparation of Pb 1.88 Zn 0.3 Nb 1.25 O 5.305 powder itself has been reported in literature.…”
