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 simultaneously 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.
一种适用于雷管以取代已知ASA混合物的起爆剂是由叠氮化铅和苯乙烯酸铅的同素异形混合晶体组成的。将含有乙酸铅的溶液和含有可溶于水的苯乙烯酸钠和叠氮化钠的溶液同时引入反应器中,使它们在糊精或羧甲基纤维素等晶体习性改良剂的存在下发生反应,从而使生成的沉淀物成为由异构混合晶体组成的均匀结晶物质。
