EVALUATION OF DOPED PERCHLORATES IN EXPERIMENTAL PHOTOFLASH COMPOSITIONS
Abstract
Effects of an oxidant containing added impurties such as Ag(+), Cu(++), and I(-) ions upon the luminosity of flash systems were tested in the following blends: (1) FP600 (60/40 KclO4/Al photoflash composition for sea level application (2) FP790 (30/20/50) Ca/Al/KclO4) photoflash composition for high altitude applications (3) FP856 (31/20/49 Al/CaF/KclO4) high altitude flash compostion. All tests were performed at sea level or at 20.9 mm Hg, simulating 80,000 feet altitude, and a/ the temperature prevailing at the Pyrotechnic Laboratory High Altitude Tank. The system 40/60 Al/KclO4 doped with Ag(+), Cu(++), or I(-) inns exhibited no increase in luminous efficiency over a non-doped control at ambient conditions. At 80,000 feet, increased efficiencies were achieved with doped systems, but the results could not be verified in a second series of tests. Within the systems 30/20/50 Ca/Al/KclO4 and 31/20/49 Al/CaF/ KclO4, the compositions containing KclO4 doped with Ag(+) ions showed the greatest increases in luminous efficiencies, ranging up to 27.0% and 29.4% respectively at 80,000 ft. However, neither system gave verifiable results on retest. The above systems doped with Cu(++) and I(-) ions gave results that were either not verifiable or else exhibited lower efficiency values.
