	Protective arrangement against projectiles, particularly hollow explosive charge projectiles - Patent 4368660
		The prior art protective arrangement is unsuitable to protect against such hollow explosive charge projectiles because, as is known, at the instant of impact of the projectile and due to the detonation of the hollow explosive charge released thereby, an energy-rich thorn or jet is formed from the lining material of the hollow explosive charge.
		Explosive materials which exhibit such characteristics are preferred for the inventive purposes because premature, unintentional and thus undesired explosion of the explosive wall layer is effectively prevented.
		The speed of movement of the wall layers 2 and 4 is dependent on the nature and quantity of the explosive material in the explosive wall layer 3 and also on the nature and quantity of the inert material of the wall layers 2 and 4.

	Æ Aeragon - Military Explosives
		Explosives are defined as materials (chemical or nuclear) that can be initiated to undergo very rapid, self-propagating decomposition that results in the formation of a more stable material, the liberation of heat, or the development of a sudden pressure effect through the action of heat on produced or adjacent gases.
		Generally, chemical explosives are substances where the fuel and oxidizer are combined in the same material thereby causing the reaction to be self-propagating.
		Black powder was the first known explosive and it continued to be the main explosive material until the late-1800s.

	S
		A high explosive which is relatively insensitive to heat and shock, usually initiated by a primary explosive or by an exploding bridgewire.
		Tracer with an igniter element, placed between the explosive in an antiaircraft projectile and the tracer element, that is designed to detonate the explosive after the projectile has passed the target point but is still high enough to be harmless to ground troops.
		Strength of materials, the capacity of materials to withstand stress (the internal force exerted by one part of an elastic body upon an adjoining part) and strain (the deformation or change in dimension occasioned by stress).

	Howstuffworks "How C-4 Works"
		The explosive material undergoes a rapid chemical reaction, either a combustion or decomposition reaction, when triggered by heat or shock energy from the detonator.
		In low explosives, such as the propellant in a bullet cartridge, the reaction occurs relatively slowly and the pressure isn't as damaging.
		Explosives experts refer to rapid explosive reactions as detonation and slower explosive reactions as deflagration.

	CMS—Checking Out the Hot Spots (Site not responding. Last check: 2007-10-13)
		High explosives are an essential component of a nuclear weapon because they initiate the nuclear reaction.
		Historically, scientists relied on rules of thumb in materials science, laboratory testing of explosives, and accident analysis to determine the dynamics of explosive materials.
		In early experiments, scientists crushed a piece of explosive material on a glass plate and identified small spots of light seen from underneath as hot spots.

	Talk:Explosive material - Wikipedia, the free encyclopedia
		Rmhermen, I removed your addition of picric acid from the primary explosives section, because I don't believe it is correct.
		It is not an explosive, it is an additive that is used to modify the physical properties of actual explosives.--BillFlis 23:49, 7 August 2006 (UTC)
		In practice, such explosives are seldom used in a pure state (mainly for safety reasons), but the other chemicals that are introduced (such as binders and plasticizers) generally do not contribute much (if at all) to the chemistry of the explosion.

	Health & Safety @ The University of Mississippi
		Explosives are a class of materials, either solids or liquids, that can undergo a rapid chemical decomposition when subject to an external force (shock, friction, sparks, etc.).
		The rate of decomposition across the explosive material travels faster than the speed of sound, and produces large amount of heat and gas.
		Factors that can transform common reagents into explosives may be as simple as extended storage time, increased storage temperatures, or allowing a material to dry out.

	: Technical Dialogue (Site not responding. Last check: 2007-10-13)
		Explosive materials are rated in terms of equivalent TNT or the mass equivalent TNT. For example, a TNT equivalent of 1.2 would mean that 1 pound of the material would be equivalent to 1.2 pounds of TNT.
		As mentioned earlier, there are different methods used to test or measure the explosive power of different explosive materials. Some of these measure all the energy produced, both the initial shock wave or pressure pulse plus the later arriving energy.
		The bottom line is that a TNT Equivalent value is useful but the user should understand the implications of using such a value and develop a solid technical understanding through study, training and experience.

	SAN FRANCISCO / Starbucks 'bomb' found to be harmless / Preliminary tests apparently find no explosive material (Site not responding. Last check: 2007-10-13)
		San Francisco authorities are no longer sure a device found in a Starbucks bathroom -- which they characterized for two days as a potentially lethal bomb -- had any explosive material in it after all, and they say the man who left it may never be charged.
		On Wednesday, agents of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives analyzed residue left behind after police blasted the device with a water cannon to render it safe.
		Some authorities suggested Wednesday that a small blast heard when police turned the water cannon on the device -- first thought to have been caused by explosive material -- was in fact the result of high-pressure water hitting flashlight batteries.
