Heat of decomposition of potassium perchlorate

Abstract

The heat of deco mposit ion of potassium perch lorate into potassium chl oride and oxygen has been determin ed in a bomb calorimeter. Th e process may be represented by t he eq uation:KCIO

High‐Performing Red‐Light‐Emitting Pyrotechnic Illuminants through the Use of Perchlorate‐Free Materials

“…Although not able to produce nitrogen gas to induce flame expansion, the thermal decomposition of KIO 4 is similar to KClO 4 in that both oxidizers readily liberate oxygen in an exothermic fashion, thus contributing energy to a given pyrotechnic system. Unlike KClO 4 , which liberates oxygen in a single‐step process around 550 °C,20 the exothermic decomposition of KIO 4 is a two‐step process, as was determined by Zachariah and co‐workers 21. A single oxygen molecule is lost around 297 °C.…”

“…With several potential candidates for replacing the M662 control in hand, the next logical step was to determine the safety in handling each during manufacturing. Accordingly, the sensitivity data of the control and successful formulations D , G , I , and J were measured and are provided below in Table 11 20. All KClO 4 ‐free formulations were less sensitive to friction compared to the control.…”

Thermodynamic properties of the perbromate and bromate ions

“…The derived data for KBr04(c) and KBr03(c) at 25°a re presented in Table V. The formation data refer to the reactions K(c) + y2Br2(l) + 202(g) ->-KBr04(c) (4) K(c) + y2Br2(l) + V202(g) -KBrOs(c) (5) and were calculated by combining the enthalpies of decomposition and AHf°(KBr(c)) = -94.12 ± 0.1 kcal mol-1. 19 The following entropies, S°293.…”

Investigating Terrestrial and Extraterrestrial Bioremediation through Microbial Action Using Raman Spectroscopy

“…Once added to the RODI water, DMM broth power was then added and autoclaved at 121 • C at 15 PSI for 15 min to ensure sterility and help with the homegenisation of the perchlorate into solution. It is noted while some perchlorate species such as potassium perchlorate and ammonium perchlorate are highly reactive to high temperatures, sodium perchlorate doesn't degrade in temperatures lower than 490 • C [52][53][54]. Perchlorate-containing broth was stored at room temperature to avoid the perchlorate falling out of solution at low-temperatures.…”
