We have demonstrated for the first time the production of silicate-lim
it NASICON [Na4Zr2(SiO4)3] in the form of thin films. The ionic conduc
tivity was investigated as a function of the temperature. The best mea
sured conductivity at 300-degrees-C is 0.5 X 10(-4) (S/cm)-1. We repor
t here on the evaluation of the mechanical properties sputtered NASICO
