<p>A powder explosive composition comprising particulate inorganic oxidizing salt, finely divided metal sensitizer and, optionally additional fuel consisting of discrete granules containing oxidizing salt and sensitizing metal coated with a tough, cohesive, resilient gelled solution of the oxidizing salt, the amount of the coating being insufficient to form a continuous gelled phase. The composition is more water resistant, less dusty and less sensitive to friction and impact than the metal sensitized powder compositions of the prior art.</p> |
