Method of connecting an alkaline beta alumina part to an alpha alumina part |
摘要 |
The alpha alumina part is heated to between 1400 DEG C and 1600 DEG C for 10 to 20 hours in a mass of alkaline carbonate or aluminate. It is then disposed in contact with a blank of the alkaline beta alumina part in a sintering enclosure suitable for establishing an atmosphere which is rich in alkaline metal and in heating this enclosure to between 1600 DEG C and 1700 DEG C for between 30 minutes and 4 hours, so as to sinter the alkaline beta alumina part while effecting the connection thereof to the alpha alumina part. The invention is used in manufacturing sodium-sulphur type electric cells.
