摘要： A method of forming a beta-alumina article includes electrophoretically depositing such material on a mandrel, exposing the deposited material promptly to a continuous flow of warm air thereby drying the deposited material, and sintering the dried material. Alternately, the deposited material is stored in a chamber purged continuously with an inert gas until the material is dried in a flow of warm dry air. Such articles are useful as solid electrolytes in sodium-sulfur and sodium halogen batteries.

摘要： A process for producing an hermetic feedthrough in a ceramic substrate by providing a sheet of liquid phase sinterable ceramic composition having a feedthrough hole, filling the feedthrough hole with refractory metal metallization material, firing the resulting structure to produce a sintered substrate and adherent metallization wherein the metallization is comprised of continuous phases of refractory metal and glass, contacting the refractory metal with electrically conductive intrusion metal and heating the resulting structure to a temperature at which the glassy phase is fluid, the refractory metal is solid, and the intrusion metal is liquid whereby the liquid metal preferentially wets the refractory metal, migrates into the metallization displacing glass and, upon subsequent solidification, partially or wholly occupies the volume space originally containing the continuous glass phase.

摘要： A sodium-sulfur cell is disclosed herein along with a method of constructing its sulfur electrode. The cell includes means containing a supply of sodium, an elongated housing joined at one end with sodium containing means, a beta-alumina electrolyte tube located within and extending from the joined end of the housing so as to define a compartment within the housing around the tube. A mixture including sulfur and an electrically conductive filler is disposed within the compartment and forms the cells sulfur electrode. In constructing this electrode, sufficient space is initially provided within the cell compartment around the beta-alumina electrolyte tube to allow for expansion of the sulfur when the latter converts from its solidified state during initial storage to its molten state during operation of the cell, thereby minimizing the possibility of damage to the electrolyte tube as a result of this expansion.

摘要： Molten sodium is filled into a reservoir insert container including a closed ended tubular portion and the sodium is solidified and the container sealed. Then an open port is provided for the insert container. The container is placed into the sodium compartment of a sodium-sulfur cell so that the tubular portion extends into the electrolytic separator tube of the cell and is spaced apart therefrom forming an annular chamber. To activate the cell, the sodium is melted and flows through the open port into the annular chamber.

摘要： Methods are described for making an improved sensing element and an improved sensor assembly for a halogen gas leak detector. The method of making an improved sensing element includes positioning at least one porous ceramic tubular element doped with sodium carbonate in a high temperature, non-reactive container, surrounding and covering the element with sodium beta-alumina particles, and baking the element in a furnace overnight at a temperature in the range from 1400.degree. C. to 1450.degree. C. The method of making an improved sensor assembly includes the above steps after which a helical heater coil is wrapped snugly around the tubular element, and a platinum wire electrode is positioned substantially within and supported by the tubular element. A suitable cement is applied over the entire helical heater coil and the immediate juxtaposed portions of the tubular element. The sensor assembly is then surrounded by and covered with sodium beta-alumina in a high temperature, non-reactive container. The cement is then cured at 1300.degree. C. for one to three hours.
