Powder form explosives

Aluminum powder forms explosive mixtures with air the lower explosive limit being ca. 35-50 g/cm3. Dust-free aluminum paste is therefore used in most applications.

Industrial explosives must be easy to shape, i.e., must have a gelatinous or powdery consistency in order to introduce the detonator or electric cap. Powder-form explosives are mostly based on ammonium nitrate and fuel components (e.g., aluminum). 

Certain types of powder-form explosives contain moisture repelling additives such as stearates in paraffinated cartridges they can be applied even under wet conditions. Non-cartridged powder form explosives must be free-flowing (-> ANFO). 

The water resistance of partly water - soluble, powder-form explosives (e.g. ammonium nitrate explosives or blasting agents) can be improved by the addition of hydrophobic or gelling agents. If e.g. - Guar Gum is added, the water entering immediately forms a gel which blocks the penetration of more water. 

The powder form explosives are cartridged and inserted in plastic hoses as a loading device. 

Combustible solid.Dust may form explosive mixture with air (flash point 334°F/168°C Fire Rating 1). Violent reaction with nitric acid forms explosive nitro materials in the presence of sulfuric acid. Dust and powder forms explosive mixture with air. Incompatible with strong acids, alkalis, aliphatic amines, alkanolamines, alkylene oxides, ammonia, epichlorohydrin, isocyanates, nitrates, nitromethane, sodium nitrite, strong oxidizers. On small fires, use dry chemical powder (such as Purple-K-Powder), Halon , alcohol-resistant foam, water spray, or CO2 extinguishers. Combustion produces phthalic anhydride and carbon oxides.

COPPER (7440-50-8) Cu The powder forms the friction-, heat-, or shock-sensitive explosive detonator, copper acetylide, with acetylene gas acetylenic compounds and ethylene oxides. The powder forms explosive materials with azides (e.g., sodium azide forms potentially explosive copper azide). Finely divided material forms friction-, heat-, or shock-sensitive explosive with powdered divided bromates, chlorates, and iodates of barimn, calcimn, magnesium, potassium, sodium, or zinc. Violent reaction, possibly explosive, when finely dispersed powder comes in contact with strong oxidizers ammonium nitrate alkynes, bromine vapor, calcium carbide, chlorine, ethylene oxide, hydrazine mononitrate, hydrogen peroxide, hydrogen sulfide, finely divided bromates, iodine, lead azide, potassium peroxide, sodium peroxide (incandescence), sulfuric acid. Incompatible with acids, anhydrous ammonia chemically active metals such as potassium, sodium, magnesium, and zinc, zirconium, strong bases.
