ION CONDUCTIVE MIXED CRYSTAL

摘要

A mixed crystal of the general composition Na1+axZr2+2/3x-axSixp3-xO12-2/3x with 0.8 ? a ?0.9 and 1.8?x?2.3, has a particularly favorable favorable conductivity, particularly when a = 0.88 and x _ 2.2 ~ This makes its use desirable as the solid electrolyte in Na/S . The high density of the single phase monoclinic crystallized material, which reaches almost 3010 g/cm3, is the result of high temperature sintering, carried out in pure oxygen.
