Impact sensitivities of mixtures of red phosphorus with various oxidants were determined in a direct drop-ball method, which indicated higher sensitivities than those determined with an indirect striker mechanism. Mixtures with silver chlorate were most sensitive, those with bromates, chlorates and chlorites were extremely sensitive, and mixtures with sodium peroxide and potassium superoxide were more sensitive than those with barium, calcium, magnesium, strontium or zinc peroxides. Mixtures with perchlorates or iodates had sensitivities comparable to those of unmixed explosives, such as lead azide, 3,5-dinitrobenzenediazonium-2-oxide etc. 

Lead Azide, Mercuric Fulminate with or without Potassium Chlorate, Lead Styphnate, Cyanuric Triazide, Tetracene and Diazodinitrophenol The following substances are also good initiating agents but have not found much use ... 

Comparing with the experiments of Grant and Tiffany [40] Harris states that silver and barium nitrocyanamides show an initiation capacity the same as that of an 80 20 mixture of mercury fulminate and potassium chlorate, but weaker than that of a mixture of lead azide and lead styphnate. This can be seen from Table 38 quoted by Harris ... 

The chlorates are strong initiators with an initiating power exceeding that of mercury fulminate and even that of lead azide. The ignition temperature of the cadmium salt is 125°C, and that of the nickel salt 170°C. Basic perchlorates of cadmium and nickel are also initiators, weaker than the chlorates, but somewhat stronger than mercury fulminate. 

II) Analysis of Mixtures Containing Lead Azide, Antimony Sulfide, Lead Sulfocyanate and Potassium Chlorate. As an example of such mixts may be cited the T—4 Primer Composition used in MI5A2 Detonator. Its aye analysis is LA 5.0, Sb sulfide 17.0,... 

Examples of very highly sensitive substances are mixture of chlorates-red phosphorus, paper cracker, lead azide, and DDNP. High sensitivity substances are dynamite(powder), PETN(powder), HMX(powder), RDX(powder), tetryKpowder), picric acid(powder), TNT(powder), and benzoyl peroxide (powder). Medium-sensitivity substances are the modem safety industrial explosives (slurry explosives, ammonium nitrate explosives), black powder, AIBN, and t-butyl-benzoate. Among low sensitivity substances are non-cap explosives dinitro benzene, dinitropentamethylenetetramine, ANFO, ammonium nitrate, nitromethane, dinitrotoluene, and cast TNT. 

Mercury fulminate has no longer a monopoly as a primer. In some of its uses it has been replaced by azides, particularly lead azide in some others chlorate primers have taken its place. Chlorates and perchlorates are also being used in industrial explosives and can now be readily manufactured by means of electrochemical processes.

COPPER (7440-50-8) Cu The powder forms the friction-, heat-, or shock-sensitive explosive detonator, copper acetylide, with acetylene gas acetylenic compounds and ethylene oxides. The powder forms explosive materials with azides (e.g., sodium azide forms potentially explosive copper azide). Finely divided material forms friction-, heat-, or shock-sensitive explosive with powdered divided bromates, chlorates, and iodates of barimn, calcimn, magnesium, potassium, sodium, or zinc. Violent reaction, possibly explosive, when finely dispersed powder comes in contact with strong oxidizers ammonium nitrate alkynes, bromine vapor, calcium carbide, chlorine, ethylene oxide, hydrazine mononitrate, hydrogen peroxide, hydrogen sulfide, finely divided bromates, iodine, lead azide, potassium peroxide, sodium peroxide (incandescence), sulfuric acid. Incompatible with acids, anhydrous ammonia chemically active metals such as potassium, sodium, magnesium, and zinc, zirconium, strong bases.
