Abstract

Na β-alumina and Na β″-alumina are the fast ion-conducting ceramics which constitute the solid electrolyte in the sodium-sulphur cell. A study has been made of the cracks (1,2) in the walls of both cycled and uncycled electrolyte tubes. Three microscopy techniques were used - scanning acoustic microscopy (SAM), optical microscopy (DM), and scanning electron microscopy (SEM). A comparison of the results is presented here. The specimens were then chemically analysed in a CAMEBAX electron-microprobe.
