Abstract : During the period of this report chemical studies were conducted to increase the lifetime of sodium ammonia solutions at elevated temperatures. This work included investigating effects of surface contaminants and solvent purification on the decomposition of sodium ammonia solutions. Quantitative measurements were made to determine the effectiveness of various cleaning procedures for glass surfaces. A search was conducted for contaminants other than water which cause decomposition of the solution. Among the investigated contaminants, tungsten has the strongest effect. Procedures for chemical analysis of sodium ammonia solutions were developed. The analysis confirmed the stability of sodium ammonia solutions up to 160 C and agreed fairly well with our conductivity data. Studies on salts in contact with sodium ammonia solutions were carried out. The electrodeless Hall effect apparatus under development to provide data on electron densities and mobilities was used to measure the Hall coefficient of mercury. This experiment was primarily considered as a final test of the apparatus.
