Abstract
The new phosphate Cs2Mn0.5Zr1.5(PO4)3 was synthesized for the first time and characterized by X-ray diffraction. Its crystal structure was refined in space group P213, Z = 4 at 25°C (a = 10.3163(1) Å, V = 1097.93(1) Å3), by the Rietveld method using the powder X-ray diffraction data. The structure is built of an octahedral-tetrahedral framework {[Mn0.5Zr1.5(PO4)3]2−}3∞ with cesium atoms being located in large cavities. The hydrolytic stability of the powdered phosphate containing 137Cs radionuclide was studied. The minimum achieved 137Cs leaching rate was 4 × 10−8 g/cm2 day.
