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 ...
The effect of additives on the burning rate of silicon-calcium sulfate pyrotechnic delay compositions

Tichapondwa, Shepherd Masimba; Focke, Walter Wilhelm; Del Fabbro, Olinto; Labuschagne, George (Wiley, 2016-08)

The effect of fuel particle size as well as the influence of inert and reactive additives on the burning rate of the Si-CaSO4 composition was evaluated. The burning rate decreased with increase in fuel particle size, while ...
