A study of the problems associated with glass seals for use in sodium/sulphur cells: An interim report (TM-MS-20)

Glass seals between b-alumina and -alumina can be made readily by using glasses such as 'Kodial' or 'ME1'. These appear satisfactory until the b-alumina adjacent to the seal is subjected to Na+ flux in a Na/S cell or a Na/b-alumina/Na test. Often, 'dendrites' appear in the b-alumina, originating at the...
