INITIATORY EXPLOSIVE FOR DETONATORS AND METHOD OF PREPARING THE SAME

摘要

An initiatory explosive suitable for use in a detonator in place of the known ASA mixture is composed of isogonous mixed crystals of lead azide and lead styphnate which can be produced by introducing sumultaneously into a reactor vessel a solution containing lead acetate and a solution containing a water-soluble styphnate and sodium azide so as to cause them to react in the presence of a crystal habit modifier such as dextrin or carboxymethyl cellulose which will cause the resulting precipitate to be a homogeneous crystalline material composed of isogonous mixed crystals.
