What is the composition of explosive?
Chemical composition A chemical explosive may consist of either a chemically pure compound, such as nitroglycerin, or a mixture of a fuel and an oxidizer, such as black powder or grain dust and air.
What is thermite classified?
Thermite (/ˈθɜːrmaɪt/) is a pyrotechnic composition of metal powder and metal oxide. Its form of action is similar to that of other fuel-oxidizer mixtures, such as black powder.
What is plastic bonded explosive?
A polymer-bonded explosive, also called PBX or plastic-bonded explosive, is an explosive material in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer.
What PBXN 103?
PBXN-103 is a low brisance explosive, having a relatively low detonation velocity of about 6000 m/s. The polymer bonded explosive PBXN-109 has a composition of 65% RDX, 21% aluminum, and 14% HTPB binder plasticized with DOA.
What is the most explosive substance?
Azidoazide azide
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 the composition of thermite?
Thermite. Schuyler S. The powder consists of aluminum and the oxide of a metal such as iron. When ignited or heated, it gives off an enormous amount of heat as a result of the chemical combination of the aluminum with the oxygen of the oxide.
What is thermite a mixture of?
The thermite mixture is a combination of finely powdered aluminum and iron(III) oxide (also called ferric oxide) in a mass ratio of 1:3 respectively, a 5-7.5 cm length of fireworks sparkler.
What is the full form of HMX?
HMX is a man-made, colorless liquid chemical which stands for High Melting Explosive. HMX will dissolve slightly in water. A very small amount of HMX will turn into a vapor in the air. It can also attach to dust or particles in air.
What is explosion in chemistry?
A chemical explosive is a compound or mixture which, upon the application of heat or shock, decomposes or rearranges with extreme rapidity, yielding much gas and heat.
What does pbxn-110 stand for?
PBXN-110 is a plastic bonded explosive (PBX) with relatively high binder content that contains 88wt% HMX and 12wt% HTPB-based binder. A pure analog of the PBXN-110 binder system was tested for comparison to the strain rate and temperature dependence of the composite PBXN-110.
What is the density of pbxn-110?
The PBXN-110 was received in 3.2-mm and 19-mm thick sheets. The average density was 1.659 g/cm3 with a standard deviation of 0.005 g/cm3. 0 20 40 60 80 100 0 1000 2000 3000 Particulate Size (microns) .
What is a PBX explosive made of?
A polymer-bonded explosive, also called PBX or plastic-bonded explosive, is an explosive material in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer. PBXs are normally used for explosive materials that are not easily melted into a casting,…
Can pbpbx powder be pressed into a specific shape?
PBX powders can be pressed into a particular shape at room temperature, when casting normally requires hazardous melting of the explosive. High pressure pressing can achieve density for the material very close to the theoretical crystal density of the base explosive material.
