Pyrochlore-type tin niobate

Acta Crystallographica Section C Crystal Structure Communications, 2001
A single crystal of Sn(1.59)Nb(1.84)O(6.35) was grown at 1273 K from a mixture of sodium niobate and tin(II) chloride. The structure is of pyrochlore type A(2)B(2)O(7). The tin is partially oxidized to tin(IV) and competes with niobium for the occupation of site B.

Pyrochlores for Advanced Oxygen Electrocatalysis

Accounts of Chemical Research, 2022
Fuel cells (FCs), water electrolyzers (WEs), unitized regenerative fuel cells (URFCs), and metal-air batteries (MABs) are among the emerging electrochemical technologies for energy storage, fuel (H2), oxidant (O2), and clean energy production. Their commercial applications are hindered by the low oxygen reduction reaction/oxygen evolution reaction (ORR/

Geochemical alteration of pyrochlore group minerals; pyrochlore subgroup

American Mineralogist, 1995
Primary alteration of uranpyrochlore from granitic pegmatites is characterized by the substitutions ADYD-+ ACaYO,ANaYF-+ ACaYO,and ANaYOI-I--+ ACaYO.Alteration occurred at "" 450-650 °C and 2-4 kbar with fluid-phase compositions characterized by relatively low aNa+,high aeaH, and high pH.
