摘要：

Na1+xZr2SixP3-xO12 are ceramic materials which are fast ionic conductors by Na+. The present work concerns the characterizations of such materials in the range x = 1.4-3.0 for their use as ion sensitive membranes. Samples were prepared by sol-gel route to obtain pellets with a high density. Characteristics, such as lattice parameters and bulk conductivity are given. Results on detection limit and selectivity of such membranes used in ISE devices are presented. The effect of the stoichiometry on electrochemical characteristics is discussed. The best performances are obtained for x = 2.0-2.2, with samples sintered at 1200 degrees C. No influence of sintering temperature is noticeable for the selectivity, excepted for proton which is less interfering after sintering at 1200 degrees C. (C) 1997 Elsevier Science S.A.
