Abstract
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.
