✦ Synopsis

The title compounds are prepared by ceramizing cementitious hydrates obtained from Nior Co-containing water solutions and cementitious mix made of Ca 3 SiO 5 and SiO 2 . Both products exhibit very low leachability, which shows the potential for trapping Ni and Co radionuclides, e.g. from nuclear power plants. -(MASSE,

Ba3Te2O6X2 is obtained by reacting TeO2 in a BaX2 flux at 1000 °C under atmospheric conditions. The samples are characterized by powder and single crystal XRD. All four compounds crystallize in the cubic space group Fd3m with Z = 16. The structures consist of a rigid ∞ 3 [M3Te2O6] 2+ framework (M: S
