MECHANISM FOR CONTROLLING THE REACTIVITY OF LEAD AZIDE

Abstract

The object was to determine how the reactivity (sensitivity) of alpha-PbN6 is influenced by particle size, the incorporation of an impurity (iron), and the method of preparation of alpha-PbN6. It was shown that (1) the sensitivity of alpha-PbN6 increases as the surface area increases, (2) iron can be carried by alpha-PbN6 either as Fe3+ or as FeN3)2+, (3) when iron is incorporated as Fe3+ up to 0.01 mole % (acidic medium) it is possible to desensitize alpha-PbN6, (4) when iron is carried by alpha-PbN6 as (FeN3)2+ a very marked sensitization results and (5) a change in the optical absorption of alpha-PbN6 is also caused by iron doping. Alpha-PbN6 prepared from lead nitrite and hydrazoic acid is the least sensitive and the absorption edge of this preparation is at 300 m millimicrons in contrast to 420 m millimicrons which is the absorption edge of alpha-PbN6 prepared by other conventional methods.
