181 Hygroscopicity
melting point:
stable modification: 70.7 °C = 159.3 °F
unstable modification: 62.1 °C = 143.8 °F
lead block test: 408 cm3 /10 g
detonation velocity, confined:
8690 m/s 28500ft/s at r = 1.60 g/cm3 decomposition temperature: 229 °C = 444 °F
impact sensitivity: 0.75 kp m = 7.4 N m
critical diameter of steel sleeve test: 6 mm
Hydrazine nitrate is readily soluble in water.
The high detonation velocity of the salt is interesting. Mixtures with
W Octogen, pressed to high density, reach more than 9000 m/s.
Hydrazine Perchlorate
perchlorate d’hydrazine
colorless crystals
empirical formula: H5N2O4Cl
molecular weight: 132.5
energy of formation: –291 kcal/kg = –1216 kJ/kg
enthalpy of formation: –318 kcal/kg = –1331 kJ/kg
oxygen balance: +24.1%
nitrogen content: 21.14%
volume of explosion gases: 838 l/kg
heat of explosion
(H2O liq.): 882 kcal/kg = 3690 kJ/kg
(H2O gas): 725 kcal/kg = 3033 kJ/kg
density: 1.83 g/cm3 melting point: 144 °C = 291 °F
lead block test: 362 cm3 /10 g
deflagration point: 272 °C = 522 °F
impact sensitivity: 0.2 kp m = 2 N m
friction sensitivity: at 1 kp = 10 N pistil load no reaction
critical diameter of steel sleeve test: 20 mm
The product is thus very sensitive.
Hygroscopicity
Hygroskopizität; hygroscopicité
Tendency of a substance to absorb moisture from its surroundings;
specifically, absorption of water vapor from atmosphere.
