摘要： A lightning arrestor insulator has a ZnO element (2) having voltage non-linear resistant characteristics embedded in an insulator body (1) and integrally fixed therein by a glassy bonding material (3). To prevent cracking due to rapid heating or cooling in manufacture or use the glassy bonding material (3) has a thermal expansion coefficient smaller than those of both the ZnO element and the insulator body. The glassy bonding material is preferably a low melting PbO-B₂O₃ system glass having a composition which separates, during solidification, low expanding ceramic crystals.

摘要： A ceramic honeycomb filter, suitable for removing fine particles contained in exhaust gases of internal combustion engines and the like, is formed of a ceramic honeycomb body (1) having a plurality of channels (2) extending from one end face (4) to another end face (4') of the body and sealing members (5, 6) fitted to the said end faces of the ceramic honeycomb body, which sealing members have sealing portions (5A, 6A) which block given channels at the end faces of the ceramic honeycomb body but do not block remaining channels opening at the same end face. The filter is produced by fitting the sealing members (5, 6) to the ceramic honeycomb body (1) and, preferably, bonding them thereto by means of an adhesive.

摘要： A beta-alumina solid electrolyte for use in sodium-sulfur battery is composed of the beta-alumina crystals having a degree of orientation toward C axis, 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 C axis, of 0.2-0.4 and has such a particle diameter distribution that the average particle diameter is 3 µm or less, the proportion of the particles having a particle diameter of 5 µm or less is 90% or more, and the maximum particle diameter is 300 µm 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 has using a magnesium-aluminum spinel as the magnesium source material and subjecting 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 sodium-sulfur battery.
