摘要： A beta-alumina solid electrolyte for use in a sodium-sulfur battery is composed of beta-alumina crystals having a degree of orientation toward the C axis thereof, of 0.2-0.4 and an aspect ratio of 4.0 or less. The beta-alumina solid electrolyte is composed of the beta-alumina crystals having a degree of orientation toward the C axis thereof, of 0.2-0.4 and has such a particle diameter distribution that the average particle diameter is 3 .mu.m or less, the proportion of the particles having a particle diameter of 5 .mu.m or less is 90% or more, and the maximum particle diameter is 300 .mu.m or less. A process for producing a beta-alumina solid electrolyte using an alumina source material, a magnesium source material and a sodium source material, uses a magnesium-aluminum spinel as the magnesium source material and subjects all materials to mixing, granulation, molding and firing to obtain a beta-alumina solid electrolyte without subjecting the materials to calcination. The beta-alumina solid electrolyte has a low electrical resistance and a large strength to internal water pressure and exhibits excellent properties when used as a diaphragm for a sodium-sulfur battery.

摘要： In a lightning arrestor insulator wherein a ZnO element having voltage non-linear resistant characteristics is embedded in an insulator body and integrally fixed with a glassy bonding material, the glassy bonding material has a thermal expansion coefficient smaller than either of those of the ZnO element and the insulator body. As the glassy bonding material, a low melting PbO-B.sub.2 O.sub.3 system glass having a composition to separate, during solidification, low expanding ceramic crystals is preferably employed.
