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
