Abstract
Abstract Explosive compositions prepared from commercially available nitric acid and a common industrial solvent are disclosed herein which exhibit exceedingly high blasting strengths. The compositions are relatively more stable than conventional shaped charge explosives such as HMX or RDX and far less expensive.
