R. Meyer J. Köhler A. Homburg Explosives

Porous Powder
Porous Powder
Poröses Pulver; poudre poreux
Special powders for exercise ammunition with a large internal surface
area and thus, a fast burning rate. The porosity is produced by adding
a soluble salt to the powder being manufactured; the salt is then
leached out again at a later stage.
Post Combustion
Nachflammen
Combustion of flammable fumes of a deflagrated or detonated explosive
with a negative oxygen balance (W also Muzzle Flash).
Potassium Chlorate
Kaliumchlorat; chlorate de potassium
KClO3
colorless crystals
molecular weight: 122.6
oxygen balance: +39.2%
density: 2.34 g/cm3 melting point: 370 °C = 700 °F
Potassium chlorate is sparingly soluble in cold water, readily soluble in
hot water, and insoluble in alcohol. It is the principal component of
W Chlorate Explosives and is an important component of primer formulations
and pyrotechnical compositions, in particular matchheads.
Potassium Nitrate
saltpetre; Kaliumnitrat; nitrate de potasse
260
KNO3
colorless crystals
molecular weight: 101.1
energy of formation: –1157 kcal/kg = – 4841 kJ/kg
enthalpy of formation: –1169 kcal/kg = – 4891 kJ/kg
oxygen balance: +39.6%
nitrogen content: 13.86%
density: 2.10 g/cm3 melting point: 314 °C = 597 °F
Potassium nitrate is readily soluble in water, sparingly soluble in alcohol,
and insoluble in ether.
