✦ Synopsis

Up to four fixed resonances are observed in the title system independent of the composition: NaZr2(P04)X (J&OS), Na3Zr1.S(P04)3 (y>O), Na4P20r (y>O) and a fourth line which we are so far unable to interpret in structural terms. The "P chemical shift parameters of NasZr,.S(P04)s are: 6= -11.9 k 0.3 ppm, Au=64 f 2 ppm and q=0.52f 0.05.

The solid solution Na,+ar,(P0,),\_,( ),has been investigated by \*)Na NMR. The parameters of the quadrupole tensor of the Na( 1) positions in NaZr2(P04), are yq= 1.2kO.l MHz and ~=0.04+0.04. Those for the Na( 1) and Na(2) sites in Na,Zr,(SiO,), are found to be Na( 1): vq= 1.04+0.1 MHz, ~=0.84?0.7; N
