22 Long
The .22 long is a variety of .22 caliber (5.6 mm) rimfire ammunition. The .22 long is the second-oldest of the surviving rimfire cartridges, dating back to 1871, when it was loaded with a bullet and of black powder, 25% more than the .22 short on which it was based. It was designed for use in revolvers, but was soon chambered in rifles as well, in which it gained a reputation as a small game cartridge. In 1887, the .22 long case was combined with the heavier bullet of the .22 extra long of 1880 to produce the .22 long rifle, giving a longer overall length and a higher muzzle energy. Many firearms designed for the .22 long rifle will chamber and fire the shorter round, though the .22 long generally does not generate sufficient energy to operate semi-automatic guns. The one prominent survivor of the .22 long is the .22 CB long, a long-cased version of the .22 CB. The original .22 long loading used the same powder charge as the .22 long rifle, .22 long bullet was sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semtex
Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications. Semtex was developed and manufactured in Czechoslovakia, originally under the name B 1 and then under the "Semtex" designation since 1964, labeled as ''SEMTEX 1A'', since 1967 as ''SEMTEX H'', and since 1987 as ''SEMTEX 10''. Originally developed for Czechoslovak military use and export, Semtex eventually became popular with armed groups and insurgents because, prior to the 2000s, it was extremely difficult to detect, as in the case of Pan Am Flight 103. Composition The composition of the two most common variants differ according to their use. The 1A (or 10) variant is used for mining, and is based mostly on crystalline PETN. The versions 1AP and 2P are formed as hexagonal booster charges; a special assembly of PETN and wax inside the charge assures high reliability for detonating cord or detonator. The H (or SE) variant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ammonium Nitrate
Ammonium nitrate is a chemical compound with the formula . It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, but does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, an industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse.Ammonium nitrate sold by ton as U.S. regulati ...

Sodium Chlorate
Sodium chlorate is an inorganic compound with the chemical formula Na ClO3. It is a white crystalline powder that is readily soluble in water. It is hygroscopic. It decomposes above 300 °C to release oxygen and leaves sodium chloride. Several hundred million tons are produced annually, mainly for applications in bleaching pulp to produce high brightness paper. Synthesis Industrially, sodium chlorate is produced by the electrolysis of concentrated sodium chloride solutions. All other processes are obsolete. The sodium chlorate process is not to be confused with the chloralkali process, which is an industrial process for the electrolytic production of sodium hydroxide and chlorine gas. The overall reaction can be simplified to the equation: First, chloride is oxidised to form intermediate hypochlorite, ClO−, which undergoes further oxidation to chlorate along two competing reaction paths: (1) Anodic chlorate formation at the boundary layer between the electrolyte and t ...
