ON LITHIUM AND SODIUM URANATES(V) AND ON STRUCTURAL RELATIONS BETWEEN THE SOMPOUND TYPES Li$sub 7$AO$sub 6$ AND Li$sub 8$AO$sub 6$ (in German)
The colored uranates(V) Li/sub 3/UO/sub 4/, Li/sub 7/UO/sub 6/, and Na/ sub 3/ UO/sub 4/ (the latter one being probably the most basic compound in the system Na/sub 2/O--U/sub 2/O/sub 5/) were thermally prepared. Their properties are described. Li/sub 7/UO/sub 6/ is isotypic with other compounds having the general formula Li/sub 7/AvO/sub 6/ (A = Sb, Bi, Nb, Ta, Ru, Os); its powder diagram is very similar to those of Li/sub 8/AlvO/sub 6/ compounds (A = Sn, Pb, Zr, Hf, Ir, Pt). Further uranates(V) were obtained from UO/sub 2/, Li/sub 2/O, and Na/sub 2/O respectively, and by reduction of Li/sub 2/UO/sub 4/ and Na/sub 2/ UO/sub 4/ by means of H/sub 2/. Alkali uranates (IV) seemed to be unstable. (auth)
