The development of the fabrication processes to produce tubes of beta-alumina ceramics for the Na/S-battery was made on the basis of the results in 1974 and in close cooperation with the Research Center of BBC in Heidelberg. The selection of raw materials, the handling of the beta-alumina powders and the shaping were clarified, except the parameters for spray drying. The results of firing in an tunnel kiln, with high pushing rates showed that the beta-alumina tubes could be produced with sufficient density, microstructure and chemical composition in a way that is transferable to a real production. Nevertheless there is the problem to reduce the consumption of the kiln furniture. It is possible to calculate the costs for producing beta-alumina tubes assuming the production of a large number of tubes and assuming that the problem of the kiln furniture is solved.
