Calcium sulfate as a possible oxidant in “green” siliconbased pyrotechnic time delay compositions

Tichapondwa, Shepherd Masimba; Focke, Walter Wilhelm; Del Fabbro, Olinto; Kelly, Cheryl (Wiley, 2015-08)

Chemical time delay detonators are used to control blasting operations in mines and quarries. Slow burning Si-BaSO4 pyrotechnic delay compositions are employed for long time delays. However, soluble barium compounds may ...
A comparative study of Si-BaSO4 and Si-CaSO4 pyrotechnic time-delay compositions

Tichapondwa, Shepherd Masimba; Focke, Walter Wilhelm; Gisby, John; Del Fabbro, Olinto; Kelly, Cheryl (Taylor and Francis, 2016-07)

Slow burning Si-BaSO4 pyrotechnic delay compositions are employed commercially for intermediate to long time delays. However, there is very little information on this composition available in open literature. The reactivity ...
Measurement and modelling of pyrotechnic time delay burning rates : application and prediction of a fast burning delay composition

Montgomery, Yolandi C.; Focke, Walter Wilhelm; Kelly, Cheryl (Wiley, 2017-11)

A predictive numerical model was implemented for a time delay based on the Si+Pb3O4 system. The reaction kinetic parameters were estimated by comparing predicted surface temperature profiles with experimental data acquired ...
Measurement and modelling of pyrotechnic time delay burning rates : method and model development

Montgomery, Yolandi C.; Focke, Walter Wilhelm; Kelly, Cheryl (Wiley, 2017-10)

The burning rates of a slow reacting Mn+Sb2O3 and a fast reacting Si+Pb3O4 time delay composition, filled into lead tubes, were measured with an infrared camera, with two thermocouples and in the form of a fully assembled ...
Mn+Sb2O3 thermite/intermetallic delay compositions

Montgomery, Yolandi C.; Focke, Walter Wilhelm; Atanasova, Maria T.; Del Fabbro, Olinto; Kelly, Cheryl (Wiley, 2016-10)

The binary Mn + Sb2O3 pyrotechnic composition was investigated for mining detonator time delay applications. EKVI thermodynamic modelling predicted two maxima in the adiabatic reaction temperature. The local maximum, at ...
