Tungsten bronze-based nuclear waste form ceramics. Part 1. Conversion of microporous tungstates to leach resistant ceramics

Removal or storage of environmental pollutants and alternative fuel sources with inorganic adsorbents via host–guest encapsulation

“…A series of papers on tungstate-bronze-based ceramics explored: their ability to simultaneously trap Cs + , Sr 2+ , and lanthanide ions; their performance as composite materials; and alternative fabrication methods. [177][178][179] These studies found that tungstate-bronze-based materials effectively immobilize Cs + ions, that they exhibit decreased durability with respect to Sr 2+ ions in acidic conditions, may achieve simultaneous trapping of lanthanides with unaffected leaching characteristics, and show a high tolerance for the inclusion of other oxides. 177,179 Composites, consisting of molybdenum-doped hexagonal tungstate bronze (MoW-HTB) and polyacrylonitrile (PAN), display excellent leach resistance, which matched or surpassed those of saturated powder phases and a titanate reference material.…”

Microsphere Zirconomolybdate Sorbents for Extraction of Lanthanides (III) from Aqueous Solutions

“…Процессы получения кристаллических и стеклокристаллических форм РАО путем вы-сокотемпературной обработки неорганических сорбентов, насыщенных катионами радиону-клидов, являются предметом ряда исследований с использованием как селективных ионитов (вольфрамовые бронзы [9], силикотитанаты [10] Cs [29].…”

Tungstate-based glass–ceramics for the immobilization of radio cesium

“…It has also been demonstrated for these materials that it is viable to prepare a durable tailored ceramic directly from Cs-and Sr-saturated hexagonal tungsten bronze (HTB) selective adsorbent compounds with general formula A x WO 3 or A x-M y W 1Ày O 3 where A cations can be Cs or Sr while M is an element that can substitute for W in the hexagonal tungsten bronze framework [38][39][40][41]. Given the potential of GCCs however, it is also of interest to explore the possibility of incorporating the saturated tungstate adsorbents into glass-ceramic composites.…”
