thermal analysis studies on the zirconium nickel alloy Potassium Perchlorate nitrocellulose pyrotechnic system
Thermochimica Acta, 1995Co-Authors: B. Berger, E.l. Charsley, J.j. Rooney, S.b. WarringtonAbstract:The zirconium/nickel alloy-Potassium Perchlorate-nitrocellulose pyrotechnic system has been studied using differential scanning calorimetry, simultaneous TG-DTA-mass spectrometry and chemical analysis using ion-specific electrodes. Quantitative measurements on the solid state reaction, in the region of 400°C, between zirconium/nickel alloy and Potassium Perchlorate have shown that a major component of the solid state reaction may be represented by the equation 9Zr + 14Ni + 8KClO4 = 9ZrO2 + 14NiO + 8KCl. DSC has been confirmed as an excellent ancillary method for the determination of the amount of Potassium Perchlorate reacted.

characterization of the zirconium Potassium Perchlorate nitrocellulose pyrotechnic system by simultaneous thermogravimetry differential thermal analysis mass spectrometry
Propellants Explosives Pyrotechnics, 1995Co-Authors: B. Berger, E.l. Charsley, S.b. WarringtonAbstract:Simultaneous thermogravimetry-differential thermal analysis-mass spectrometry have been used to characterize the zirconium/Potassium Perchlorate/nitrocellulose pyrotechnic system, by examining the components and their binary and ternary combinations under inert atmosphere conditions. Zirconium and Potassium Perchlorate were found to give an exothermic solid state reaction between 300°C and 500°C and the reaction was influenced significantly by the presence of small amounts of nitrocellulose. The decomposition of unreacted Potassium Perchlorate was observed to commence in the latter stages of the reaction and was found to be catalyzed by presence of the reaction products ZrO2 and KCl.

Quantitative studies on the zirconium - Potassium Perchlorate - nitrocellulose pyrotechnic system using differential scanning calorimetry and chemical analysis
Thermochimica Acta, 1995Co-Authors: B. Berger, E.l. Charsley, J.j. Rooney, S.b. WarringtonAbstract:Abstract Differential scanning calorimetry and chemical analysis, using ion specific electrodes, have been used to follow quantitatively the solid state reaction in the region of 400°C, between zirconium and Potassium Perchlorate in the presence of nitrocellulose. Comparison of the amount of Potassium chloride formed in the reaction with the amount of Perchlorate reacted has shown that the solid state reaction may be represented by the equation 2Zr + KClO 4 → 2ZrO 2 + KCl. DSC has been found to provide an excellent ancillary method for the determination of the amount of Potassium Perchlorate reacted.

Investigation of the thermal degradation of the aged pyrotechnic titanium hydride/Potassium Perchlorate
Journal of Thermal Analysis and Calorimetry, 2006Co-Authors: Daniel N. Sorensen, A. P. Quebral, E. E. Baroody, W. B. SanbornAbstract:Titanium hydride/Potassium Perchlorate (THPP) is a pressure producing pyrotechnic composition consisting of a mixture of titanium dihydride and Potassium Perchlorate with a small percentage of a Viton binder. The initial phase of the study focused upon chemical analysis of THPP downloaded from parts ranging up to 25 years in age. The DSC curves were too erratic for kinetic analysis; however, high resolution TG curves for the THPP samples revealed a significant difference in the temperature at which the aged materials began displaying mass loss. Isothermal DTA and variable heating rate TG kinetic analysis were employed to determine the activation energy of the THPP.
