Caps, blasting primer

Mercury fulminate (Figure 3.36) was one of the earliest of the initiating explosives. It was used extensively in blasting caps and primers. It has since been displaced by lead azide in modem initiators. Mercury fulminate is made by dissolving mercury in nitric acid, forming a mercury nitrate solution. This solution is then poured into alcohol, forming mercury fulminate, which then precipitates out of the solution. [Pg.49]

There is a vast array of energetic materiald that falls mder the sensitivity classification of primary explosives. When the complexity and extent of primer explosives are multiplied by all the different ways manufacturers use initiation devices, the subject becomes extremely voluminous. Rather than cover all these materials and their applications, we noil concentrate on only those most commonly used in the construction of such initiation systems as blasting caps and primers. Figure 13 contains some of the physical attributes of common primary explosives. [Pg.41]

Potassium Dinitroazidophenolate (called Potassium Dinitrophenylazide by McNutt). K0,N3.CgH2(N02)2. It was proposed as an ingredient of primer mixts suitable for small srms and artillery ammo, commercial blasting caps, etc. Typical mixts suggested were 1)K Dinitroazidophenolate 16, Basic Pb Styphnate 15, Ba nitrate 40, Sb silicide 29% 2) K Dinitroazidophenolate 17, Basic Pb Styphnate 18, Ba nitrate 35, Pb thiocyanide 5, ground glass 25%...

Detonators are used to detonate high explosives. Stab detonators are initiated by sharp firing pins and are used in explosive trains of different types of fuses. Flash detonators are initiated by flames produced by safety fuses, primers, or delay elements. A special type of flash detonator ignited by the flame of a safety fuse is called a blasting cap. Detonators are primarily composed of three types of explosives including sinoxid mixtures, lead azide-based mixtures, and mercury fulminate-based mixtures. [Pg.50]

Tetryl (C7H5N508) is a pale yellow crystalline solid. It is moderately sensitive to initiation by friction and percussion and is used in the form of pressed pellets as primers for explosive compositions that are less sensitive to initiation. It is slightly more sensitive than picric acid and considerably more sensitive than TNT. In the early 1900s, tetryl was used as base charges for blasting caps but now has been replaced by PETN and RDX. During World War II, tetryl was used as a component of explosive mixtures. [Pg.53]

Dynamite primer and in Gt Britain primer cartridge" For its preparation, one cuts across a safety fuse with a clean sharp knife (or fuse-cutter) a required length and inserts freshly cut end into open end of blasting cap. Using a proper crimping tool, the cap is crimped near its open end to hold the fuse securely in position. This combination is... [Pg.734]
