In this report, further research findings are given on (1) the development of binder systems for extrusion and the preliminary extrusion of conductive ..beta..'-alumina tubing, (2) low- and high-temperature sintering methods, (3) mechanical properties of ..beta..'-alumina, especially its resistance to thermal shock, (4) the relationship between degree of conversion to ..beta..'-alumina, grain size, and conductivity, (5) the durability of ..beta..'-alumina in Na--S cells, (6) the improvement of cell rechargeability with the use of shaped porous electrodes, (7) the influence of impurities on ceramic degradation during cell operation, and (8) the use of coatings on metal or of inherently stable metal oxides in the design of the sulfur--polysulfide container. The cell testing program has yielded additional promising results, and more information has been accumulated concerning the reasons for cell failure. The oldest laboratory cell is now in its 18th month of operation, has passed over 1060 Ah/cm/sup 2/ discharge and completed more than 6400 cycles. (GRA)
