Abstract:

Intensive investigations were conducted on improving the thermal stability and crystallization of AlH3. Areas considered included the solubility in various solvents with and without addition agents, thermal seeding, growth processes, decomposition processes, aging, surface oxidation and treatment, and surveillance of both neat and formulated propellants at 25 and 40 C. A study of the kinetics of AlH3 and BeH3 using flash heating with UV spectroscopy showed the existence of AlH, BeH and BeH at 2,500 K. The reaction of tris-I with nitroform gave a new liquid oxidizer or plasticizer. The heat of formation of AlBH43, Hybaline A-4, C2F6 radical, INFO-635P, and BTU, high temperature enthalpies of allotropic forms of BeCl2, and the enthalpies and heat capacities of Al are reported. In the JANAF Tables, area, a summary of Series C and D of the Propellant Ingredients and 4 supplements of the Thermochemical Tables are given. The toxicological research was concentrated on Be-containing materials using controlled samples of the oxide, some hydrides, metal and firing residues. The animal response of the low-fired oxide is entirely different than the high-fired oxide and evidence of carcinogenic tumors was detected in the lung tissue of animals exposed to low-fired materials.
