XPS and NEXAFS Studies of Zn-Doped Bismuth Iron Tantalate Pyrochlore

open access: yesInorganics, 2023
The effect of Zn-doping on the phase composition and optical properties of the Bi2ZnxFe1-xTa2O9.5-Δ (x = 0.3, 0.5, 0.7) was studied. XRD data showed that the samples crystallize in the structural type of pyrochlore (sp. gr.Fd-3m). For all the samples, an

THE PYROCHLORE SUPERGROUP OF MINERALS: NOMENCLATURE

open access: yesThe Canadian Mineralogist, 2010
A new scheme of nomenclature for the pyrochlore supergroup, approved by the CNMNC-IMA, is based on the ions at the A, B and Y sites. What has been referred to until now as the pyrochlore group should be referred to as the pyrochlore supergroup, and the subgroups should be changed to groups.

NEW DATA ON PYROCHLORE OF ALKALI PEGMATITES AND ORE ZONES OF THE VISHNEVYE MOUNTAINS (SOUTHERN URALS) [PDF]

open access: yesМинералогия, 2018
The minerals of the pyrochlore group are abundant in rocks of the Vishnevogorsk alkaline complex – miaskites, mica rocks, carbonatites, and their pegmatites. Several generations of pyrochlore can be found in complex pegmatite bodies.

Insight Into Disorder, Stress and Strain of Radiation Damaged Pyrochlores: A Possible Mechanism for the Appearance of Defect Fluorite

open access: yesFrontiers in Chemistry, 2021
We have examined the irradiation response of a titanate and zirconate pyrochlore—both of which are well studied in the literature individually—in an attempt to define the appearance of defect fluorite in zirconate pyrochlores. To our knowledge this study
