Nonmetallic Material Compatibility with Liquid Fluorine

Description: Static tests were made on the compatibility of liquid fluorine with several nonmetallic materials at -3200 F and at pressures of 0 and 1500 pounds per square inch gage. The results are compared with those from previous work with gaseous fluorine at the same pressures, but at atmospheric temperature. In general, although environmental effects were not always consistent, reactivity was least with the low-temperature, low-pressure liquid fluorine. Reactivity was greatest with the warm, high-pressure gaseous fluorine.

The Detection of Small Amounts of Fluorine in Large Amounts of Chlorine

Description: Abstract: "Tests have been developed for both the qualitative detection and quantitative determination of fluorine in chlorine. The qualitative test is made by passing the gas through manganous chloride. If the pink solid tubes brown there is greater than 0.5 percent of fluorine in the gas. The quantitative test is a modification of the Steiger and Marvin Test with oxidized titanium solution."

Material compatibility with gaseous fluorine

Description: Static tests on the compatibility of fluorine with non-metals at atmospheric temperature eliminated many materials from further consideration for use in fluorine systems. Several materials were found compatible at atmospheric pressures. Only Teflon and ruby (aluminum oxide) were compatible at 1500 pounds per square inch gage.

Literature Survey for the Fluorine Generation Program

Description: The following report discusses the production of three types of fluorine cells for the Manhattan Project's fluorine generation program: the high temperature fluorine cell operating at a temperature of 240 C., the low temperature cell operating at a temperature of 30 C., and the medium temperature cell operating at a temperature of 100 C.

Boundary lubrication of steel with fluorine- and chlorine-substituted methane and ethane gases

Description: Report presenting a study of the lubrication of steel by a series of stable fluorine- and chlorine-substituted methane and ethane derivatives. Several compounds containing fluorine and two or more chlorine atoms per molecule functioned as boundary lubricants to reduce friction and to prevent surface welding and metal transfer.

Rate of reaction of gaseous fluorine with water vapor at 35 degrees C

Description: Report presenting testing of fluorine and water vapor, which react extremely slowly or not at all in the gas phase at 35 degrees Celsius at partial pressures of the reactants up to 40 mm of mercury. Results regarding the gross nature of the reaction, order of the reaction, kinetics of surface and gas-phase reactions, relative importance of surface and gas-phase reactions, and rate of surface reaction are provided.

Experimental rocket performance with 15 percent fluorine - 85 percent oxygen and JP4

Description: From Summary: "Experimental performance of a rocket engine using 15 percent fluorine-85 percent oxygen and JP-4 was compared with that obtained using oxygen and JP-4. The regeneratively cooled engine was operated at 5000 pounds thrust and a chamber pressure of 350 pounds per square inch absolute. The peak specific impulse from 15 percent fluorine was 251 pound-seconds per pound. This is an increase of 3.3 percent over the 243 pound-seconds per pound obtained with fluorine."

Material compatibility with gaseous fluorine

Description: Report presenting static tests on the compatibility of gaseous fluorine with various liquids, solid plastics, waxes, and greases at pressures of 0 and 1500 pounds per square inch gage and atmospheric temperature. Several materials were found to be compatible at atmospheric pressure, but only Teflon and ruby were compatible under static conditions at 1500 pounds per square inch gage.

Experimental performance of fluorine-oxygen with JP4 fuel in a rocket engine

Description: Report presenting the performance increase resulting from the addition of fluorine to the oxygen-JP4 rocket propellant combination evaluated experimentally in a 1000-pound-thrust engine with 0, 30, and 70 percent of fluorine by weight in the oxidant. Maximum specific impulse values obtained were 259, 278, and 287 pound-seconds per pound, respectively, at a combustion pressure of 600 pounds per square inch absolute.

Experimental performance of liquid fluorine-liquid ammonia propellant combination in 1000-pound-thrust rocket engines

Description: "The performance of liquid fluorine and liquid ammonia as a propellant combination was evaluated in 1000-pound-thrust rocket engines operated at a chamber pressure of 600 pounds per square inch absolute. Values of specific impulse, characteristic velocity, thrust coefficient, and heat rejection were obtained as functions of propellant mixture ratio for each of four injectors: a triplet, a showerhead, and two like-on-like types" (p. 1).

Fluorine Adsorption and Diffusion in Polycrystalline Silica

Description: The measurement of fluorine penetration into archeological flint artifacts using Nuclear Reaction Analysis (NRA) has been reported to be a potential dating method. However, the mechanism of how fluorine is incorporated into the flint surface, and finally transported into the bulk is not well understood. This research focuses on the study of the fluorine uptake phenomenon of flint mineral in aqueous fluoride solutions. Both theoretical and experimental approaches have been carried out. In a theoretical approach, a pipe-diffusion model was used to simulate the complicated fluorine transportation problem in flint, in which several diffusion mechanisms may be involved.
