Protocol for the full quantitative analysis of flash compositions

F. Lederle, J. C. Namyslo and E. G. Huebner Abstract. This paper describes a protocol for the full quantitative analysis of a flash composition. The protocol is based on the separation of the components by basic laboratory handling procedures as a first step. Subsequently, modern and routinely available instrumental analytics are used to quantitatively analyse …

Decomposition Kinetics of Pyrotechnic Mixture from Sound-Producing Fire Crackers

A. Jeya Rajendran, T. Lekshmana Thanulingam, A. Meisudar and U. Manikandan Abstract: Dynamic, non-isothermal analysis of the pyrotechnic mixture of a sound-producing fire cracker, KNO3/Al/S/H3BO3,was carried out under N2 atmosphere by using a simultaneous thermogravimetric and differential thermal analyser. Intermediates and the residue formed in each stage of thermal decomposition of the pyrotechnic mixture were …

Metal–Fluorocarbon Pyrolants. XV: Combustion of two Ytterbium–Halocarbon Formulations

Ernst-Christian Koch,Volker Weiser, Evelin Roth, Sebastian Knapp, Joost van Lingen and Jacco Moorhoff Abstract: Binary pyrolants based on ytterbium and either polytetrafluoroethylene or hexachloroethane yield a broad stable combustion regime with intense luminous flames. Combustion temperatures have been determined spectroscopically for both pyrolant types. The temperature correlates with the burn rate of the pyrolant. The UV-Vis spectra …
