High density explosives
WebWhen I looked at the density ranges for emulsions I found the following: A: The density ranges were from .8 g/cc to 1.3 g/cc B: 95% were below 1.2 g/cc with the lowest being .8 g/cc C: Over 70% on the emulsions … Webexplosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical …
