Abstract

The results from a study on the combustion of the ferrosilicon-miniun delay powder which was examined under the various conditions are as follows. 1. It has been found that in case of these delay powders, decomposition of oxidiging agents occurs first and then reducing agents are oxidized by the gases evolved from the oxidizing agents and by the oxygen in air. Therefore, the main reactions are heterogenous reaction and especially He gas phase plays an important role in combustion reactions of delay Powders. 2. In case the loading pressure is below 100kg per a detonator, the dispresion of burning time is large. 3. Little or no increase in humidity was observed on daily measurement during six month preservation tests. 4. The amperage of electric current for igniting the fuse head has no effect on the burning time of delay conposition itself changed in the detonator.
