摘要

Work is essentially complete on a generalized technique for the analytical solution of complex multi-element chemical equilibrium under all conditions of pressure, temperature, and mass balance. The program written for the IBM 7090 uses a unique technique of 'majors and minors' to automatically guarantee convergence. Preliminary laboratory work on the study of the O2/C2F4 flame is under way. The study relates to the ablative properties of Teflon, C2F4 being the major product of high temperature degradation. Laboratory equipment and furniture have been procured for the activation of the Lunar Resources Laboratory. The objectives of the program are to determine the feasibility of obtaining from the lunar crust oxygen for breathing and propellant usage, water for drinking or cosmetic uses, and materials for construction. Possible routes to oxygen from lunar rock (silicates) include direct thermal conversion, reaction with hydrogen at elevated temperatures followed by electrolysis of water, electrolysis of molten silicates, and displacement of oxygen with fluorine.
