Effect of excess Mg and Excess Nb incorporation into the B-site of pyrochlore in the Pb-Mg-Nb-O system

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2002
In the Pb-Mg-Nb-O system, excess Mg and excess Nb incorporation into the B-site of PMN pyrochlore were investigated along the compositons of Pb1.83Mg0.29+xNb1.71-xO6.39-1.5x where x=0.1, 0.2, 0.3, 0.4, 0.522 and Pb1.83Mg0.29-xNb1.71+xO6.39+1.5x where x=0.

Immobilization of High‐Halide Nuclear Waste: A Review of Recent Advances of Relevant Material Design and Processing

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 5, September 2026.
Qualitative comparison on the key properties of various waste form options for the immobilization of high‐halide nuclear waste. ABSTRACT The safe disposal of halide‐containing nuclear wastes is one of the key challenges to address not just for the electrochemical reprocessing of used nuclear fuel, but also for the future implementation of molten salt ...

Topological thermal Hall effect of magnetic monopoles in the pyrochlore U(1) spin liquid

open access: yesPhysical Review Research, 2020
“Magnetic monopole” is an exotic quantum excitation in three-dimensional U(1) spin liquid, and its emergence is purely of quantum origin and has no classical analog.

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

NEXAFS and XPS Studies of Co Doped Bismuth Magnesium Tantalate Pyrochlores

open access: yesChemistry
Co doped bismuth magnesium tantalate with a pyrochlore structure (sp. gr. Fd-3m) was synthesized for the first time using the standard ceramic method. Single phase Bi2Mg1−xCoxTa2O9 samples were found to be formed when x < 0.7 in the X-ray phase analysis.
