Theory of Coloured Flame Production

BE Douda Abstract: The theories and attributes associated with the production of colored flames are presented. Particular attention is given to flames containing strontium (red), barium (green), sodium (yellow) and copper (green or blue). Thermal excitation of vaporized neutral atoms, molecules and ions is correlated with the emission of atomic, band and ionic spectra. These …

Some Factors Affecting the Performance of a Class of Ammonium Perchlorate-Based Pyrotechnic Strobe Compositions

Richard Harrison Abstract: Despite well over a century of research, which has seen the development of many effective pyrotechnic strobe compositions, there is as yet very little understanding of the strobe mechanism. In the past, theoretical models have been developed, but are here shown to be unable to explain many of the observed characteristics. Factors …

A Thermal Study of Mixtures of Micron-sized Copper (II) Oxide, Aluminum and Magnalium

Richard Harrison Abstract: The reaction temperature in ignited samples of thermite compositions containing CuO and varying proportions of aluminum and magnalium was monitored at 1ms intervals by means of small embedded thermocouples. Analysis of the temperature profiles reveals that, in all cases, an exothermic minimum in the region of 950 K provides a significant contribution …
