摘要：

NASICON (Na(1+x)Zr2Si(x)P(3-x)O12) is a new ceramic material and is a fast ionic conductor by Na+. It was initially proposed for use as an ion-sensitive membrane for ISE or ISFET devices some years ago. The sol-gel route is used here to prepare high-density samples. Some physicochemical characteristics such as structure, conductivity, and solubility are described. Results on ISEs made with this material are presented including ion-exchange kinetics, detection limit, and selectivity coefficients. A sintering temperature influence is observed. The performance characteristics are compared to those of a commercial glass membrane; the detection limit is slightly poorer than for the commercial ISEs but selectivity is always better (up to 10 times). A considerable sintering temperature influence is observed on the interfering proton phenomenon: the higher the temperature, the smaller the effect.
