Sodium zirconium phosphate (NZP) is a potential material for immobilization of nuclear effluents. The Structure of polycrystalline phase of barium containing NZP was determined on the basis of crystal data of solid state simulated waste forms. The crystal
structure of Na1-xBax/2Zr2P3O12 (x=0.1-1.0) has been investigated using General Structure Analysis System (GSAS) programming. The BaNZP phase crystallizes in the space group R-3c and Z=6. Powder diffraction data have been subjected to Rietveld refinement to arrive at a satisfactory structural convergence of R-factors. The unit cell volume and polyhedral (ZrO6 and PO4) distortion increases with rise in the mole % of Ba2+ in the NZP matrix. SEM, TEM and EDX analysis provide analytical evidence of barium in the matrix.
