Examples include primary explosives such as nitroglycerin that can detonate with little or no stimulus and secondary explosives such as dynamite (trinitrotoluene, TNT) that require a strong shock (from a detonator such as a blasting cap). Low explosives change into gases by burning or combustion.
What is explosive oxidizer?
An oxidizer is a pure substance (molecule) that in a chemical reaction can contribute some atoms of one or more oxidizing elements, in which the fuel component of the explosive burns. On the simplest level, the oxidizer may itself be an oxidizing element, such as gaseous or liquid oxygen.
What chemicals cause mixed explosions?
Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents. White (also called yellow) P should be stored under water, in glass, because it is pyrophoric.
What are types of explosives?
explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.What is the most explosive material?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
What is fuel and oxidizer?
Fuel and oxidizers are the propellants. Fuel is the substance that burns to create the expanding gasses that power a rocket engine. … Oxidizers become necessary in the vacuum of space, where there is no oxygen to help ignite the fuel. The simplest type of fuel and oxidizer would be liquid hydrogen and liquid oxygen.
What is c4 made of?
C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source.
What is explosion and give the classification of explosion?
An explosion is a sudden and rapid increase in volume and release of energy in an extreme manner. … Explosions can be: chemical – high explosives, gas ignition, and fine particulate or dust sulphide dust ignition (SDI)What are explosive chemicals?
An explosive chemical is a solid or liquid chemical which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
What is dynamite made of?Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder.
Article first time published onWhat are the two types of explosives?
6.3 Explosives There are two major categories, high explosives and low explosives. High explosives are further divided into initiating, or primary, high explosives and secondary high explosives.
Which definition describes explosive material quizlet?
an explosive. An explosive is a chemical or mixture of chemicals that react violently and produce an explosion. Accelerants are chemicals used to make a fire burn hotter/faster than a natural fire.
How is nitrogen explosive?
The explosiveness of nitrogen-containing compounds is driven by the huge release of energy that occurs when the nitrogen-nitrogen triple bonds form. … A second factor makes nitrogen compounds explosive: the newly formed nitrogen molecules form a gas, which can expand very quickly and form a shock wave.
Can formic acid explode?
Formic acid (98-100%) decomposes to carbon monoxide and water after prolonged periods of storage. The gas builds up significant pressure to cause explosion and potential injury.
Is nano3 explosive?
Sodium nitrate appears as a white crystalline solid. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire.
What is the most explosive gas?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
What does TNT stand for?
trinitrotoluene (TNT), a pale yellow, solid organic nitrogen compound used chiefly as an explosive, prepared by stepwise nitration of toluene.
Is primer cord explosive?
Primaline® Detonating Cord PRIMALINE det cords are flexible linear explosives with a core of PETN explosive encased in a plastic outer jacket. PRIMALINE detonating cords are designed for use as trunklines and/or downlines in abrasive mining, quarrying and construction applications.
Are C4 and Semtex the same thing?
The C4 plastic explosive is of the same type as Semtex, a favourite of the IRA and other terrorists. … The material has two main components: RDX, or Cyclonite, the explosive similar to that found in fireworks, and PETN, or Pentaerythrite.
Can I eat C4?
When ingested, C4 results in serious CNS effects such as generalized seizures in addition to renal and GI symptoms. Based on previous reports, the toxic presentation is transient and treatment is supportive. Critical actions include airway maintenance, seizure control, and fluid resuscitation.
What is c6 explosive?
C-6 “Flatfire” Plastic Explosive is grey block of plastique, can be detonated by timer, tripwire or signal. The basic blast radius for C-6 is 5m.
What is oxidizer made of?
Liquid oxygen (LOX) serves as the oxidizer. The boosters, on the other hand, use aluminum as fuel with ammonium perchlorate as the oxidizer, mixed with a binder that creates one homogenous solid propellant. Hydrogen, the fuel for the main engines, is the lightest element and normally exists as a gas.
Are oxidizers explosive?
It is highly reactive and impact or high temperatures can cause violent decomposition or explosion. It can form shock-sensitive mixtures with finely powdered metals, metal oxides, strong reducing agents, sulfur and phosphorus.
What is oxidizer in rocket fuel?
An oxidizer is a type of chemical which a fuel requires to burn. Most types of burning on Earth use oxygen, which is prevalent in the atmosphere. However in space there is no atmosphere to provide oxygen or other oxidizers so rockets need to carry up their own oxidizers.
Which xenon compound is explosive?
Xenon trioxide is an unstable compound of xenon in its +6 oxidation state. It is a very powerful oxidizing agent, and liberates oxygen from water slowly, accelerated by exposure to sunlight. It is dangerously explosive upon contact with organic materials.
What are the elements of explosion?
Fires and explosions require three elements in order to occur (the ‘fire triangle’): oxygen, fuel and heat.
What are the four types of explosives?
- blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture); …
- perforating explosives (intended for use in the oil and gas well industry); …
- special-application explosives (high explosives used for other applications, including primary explosives).
What is an explosion give an example?
An explosion is a sudden, violent burst of energy, for example one caused by a bomb. A second explosion came minutes later and we were enveloped in a dust cloud. Three people have been killed in a bomb explosion in northwest Spain.
What is a secondary explosive?
What are secondary explosive devices? Secondary explosive devices are bombs placed at the scene of an ongoing emergency response that are intended to cause casualties among responders.
What is mechanical explosion?
Overview. A mechanical explosion is a rapid, uniform expansion of a gas that takes place without chemical reaction. The process is very rapid such that heat and mass transfer to or from the expanding gas can be considered negligible.
What definition describes explosive material?
An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
