ABSTRACT:
The spray-drying of a feed liquid mixture containing dissolved feed elements is used to produce precursor powders of Na.sup.+ -super conducting sodium gadolinium silicate (Na.sub.5 GdSi.sub.4 O.sub.12), (NGS), and sodium yttrium silicate (Na.sub.5 YSi.sub.4 O.sub.12), NYS. Using these powders, very dense (>97% theoretical) solids are obtained on sintering. The resistivities of the NGS and NYS polycrystalline ceramics are 5 and 7 (.OMEGA. cm) respectively at 300.degree. C. and are dependent on the f(NGS) or f(NYS) values. In the case of NYS, the resistivity/f(NYS) relationship takes the form ##EQU1## indicative of resistive and conductive phases mixed more in parallel than in series.
