Popis:	The orthophosphate solid solution phase, Na /SUB 5-4x/ Zr /SUB 1+x/ (PO/sub 4/)/sub 3/: 0.04 less than or equal to x less than or equal to 0.15 has trigonal symmetry with an apparent one dimensional incommensurate superstructure parallel to c /SUB HEX/ . Using selected area electron diffraction patterns as a guide, an indexing scheme for the powder X-ray data has been devised. The parameter kappa=/iota/supercell//iota/subcell varies smoothly with composition from about 10.4 at x = 0.04 to about4.4 at x = 0.11 and is believed to originate in ordering of the extra interstitial Zr/sup 4 +/ ions. The Na/sup +/ ion conductivity increases gradually with x and for x = 0.108 varies from about5x10/sup -8/ ohm/sup -1/ cm/sup -1/ at 25/sup 0/C to about1x10/sup -3/ ohm/sup -1/ cm/sup -1/ at 300/sup 0/C.
