  • Ion conductive mixed crystal
    Patent number: 4394280
    Abstract: A mixed crystal of the general compositionNa.sub.1+ax Zr.sub.2+22/3x-ax Si.sub.x P.sub.3-x O.sub.12-2/3xwith 0.8.ltoreq.a.ltoreq.0.9 and 1.8.ltoreq.x.ltoreq.2.3, has a particularly favorable Na-ion conductivity, particularly when a=0.88 and x=2.2. This makes its use desirable as the solid electrolyte in Na/S cells. The high density of the single phase monoclinic crystallized material, which reaches almost 3.10 g/cm.sup.3, is the result of high temperature sintering, carried out in pure oxygen.
