The synthesis of Na containing Nasicon-type phases of the form Na[sub x]M[prime](II)[sub x]M[double prime](III)[sub 2[minus]x](SO[sub 4])[sub 3[minus]y](SeO[sub 4])[sub y] (M[prime] = Mg, Zn, Cd, Mn; M[double prime] = Al, Cr, Fe, In, Yb; 0 [le] x [le] 1.75; 0 [le] y [le] 3) is reported. The conductivities of a range of samples have been measured, with the highest value observed at 200[degrees]C being 2 x 10[sup [minus]4] [Omega][sup [minus]1] cm[sup [minus]1] for Na[sub 1.75]Mg[sub 1.75]Cr[sub 0.25](SO[sub 4])[sub 3]. The range of x for which single phase samples are observed depends on the nature of M[prime] and M[double prime], and on the value of y. Attempts to increase the Na content, and so increase the conductivity, by partially substituting the (S, Se)O[sub 4] groups by PO[sub 4] or SiO[sub 4] have proven unsuccessful.
