Abstract : A successful 68-hr seal was produced in a cell containing all components--potassium, mercury, matrix, and electrolyte. All of the ceramic materials readily available were investigated for chemical compatibility, mechanical strength, and conductivity. This led to the selection of magnesia as a suitable matrix material. Investigations were also conducted on matrix configurations to determine the most desirable configuration for mechanical strength without sacrificing electrical properties. This led to selection of a matrix with reinforcing ribs. Conductivity studies on new ceramic materials yielded encouraging results. Internal resistances approximately 1/3 to 1/2 of those currently found are predicted. A cell was designed which could be used for both the single and multiple cell tests. (Author)
