Synthesis and study of the phosphate Cs2Mn0.5Zr1.5(PO4)3

Crystal structure of langbeinite-related Rb0.743K0.845Co0.293Ti1.707(PO4)3

“…It should be noted that compounds with a langbeinite-type structure are prospects for use as a matrix for the storage of nuclear waste (Orlova et al, 2011). Zaripov et al (2009) and Ogorodnyk et al (2007a) proved that caesium can be introduced into the cavity of a langbeinite framework that can be used for the immobilization of 137 Cs in an inert matrix for safe disposal.…”

CsAlZr2(PO4)4: an anhydrous aluminium zirconium phosphate with a novel three-dimensional framework

“…Anhydrous inorganic metal phosphates prepared by hightemperature solid-state reactions have been the subject of intensive research activities and their number has grown steadily (Kanatzidis et al, 2007;Ettis et al, 2003;Zaripov et al, 2009;Zatovsky et al, 2007;Xiong et al, 2007;Ranmohotti et al, 2006;Parreu et al, 2006). The crystal chemistry of these compounds with partial structures mainly built from PO 4 tetrahedral building units reveals a large structural variety, which is usually accompanied by intriguing magnetism, electric, optical and thermal expansion properties.…”

Natural Clay Minerals as a Starting Material for Matrices for the Immobilization of Radioactive Waste from Pyrochemical Processing of SNF

“…Existing work on the properties of crystalline ceramics for immobilizing radioactive waste is related to mineral-like phases such as pyrochlore, perovskite, zirconolite, zirconium dioxide, garnet, hollandite, pollucite, murataite, monazite, and NZP [10][11][12][13][14][15][16][17]. The authors of [18] developed a method for immobilizing chloride salts using zeolite with sodalite as the final form of the transformed chlorides.…”
