283 Silver Azide
Shot Firer
Sprengmeister; boutefeu
That qualified person in charge of and responsible for the loading and
firing of a blast (same as a W Blaster).
Shunt
A short-circuiting device provided on the free ends of the leg wires of
electric blasting caps to protect them from accidental initiation by
extraneous electricity.
Silver Acetylide
silver carbide; Silberkarbid; Acetylensilber; acétylure dargent
C2Ag2
molecular weight: 239.8
oxygen balance:–26.7%
deflagration point: 200 °C = 392 °F
Silver carbide is very sensitive to impact. It is prepared by bubbling
acetylene through a slightly acidic or neutral silver nitrate solution.
Silver Azide
Silberazid; azoture dargent
AgN3
molecular weight: 149.9
nitrogen content: 28.03%
volume of detonation gases: 224 l/kg
density: 5.1 g/cm3 melting point: 251 °C = 484 °F
lead block test: 115 cm3 /10 g
deflagration point: 273 °C = 523 °F
Silver azide is sensitive to light, insoluble in water, and soluble in
ammonia, from which it can be recrystallized. It is prepared from
sodium azide and solutions of silver salts (depending on the working
conditions) as a cheesy, amorphous precipitate.
It gives a very satisfactory initiating effect which is superior to that of
lead azide. Nevertheless, its practical use is limited, because of its
high sensitivity to friction, and because its particular texture makes the
dosing difficult.
