Tannerite is the brand name of a binary explosive marketed primarily for making exploding targets for firearms practice.〔https://www.tannerite.com Tannerite Company (Pleasant Hill Oregon USA) website〕 It is a patented combination of ammonium nitrate (an oxidizer) and aluminium powder (a fuel) that is supplied as two separate powders that are mixed and shaken to produce an explosive. The combination is relatively stable when subjected to forces less severe than a high-velocity bullet impact, such as a hammer blow, being dropped, or impact from a low-velocity bullet or shotgun blast.〔 It is also not flammable – an explosion cannot be created by a burning fuse or electricity.〔 Because it is sold as two separate powders, it can be transported and sold in many places without the legal restrictions that would otherwise apply to explosives.〔 Other combination explosives are generically referred to as Tannerite.〔Mike M. Ahlers and Rene Marsh, ("Exploding targets: shooting aid or a 'bomb kit for dummies? ), CNN, September 6, 2013.〕 ==Uses== Tannerite is intended to detonate when shot by a high-velocity firearm cartridge. Low-velocity shotgun ammunition will not initiate a detonation.〔 Tannerite detonations occur at a very high velocity, producing a large explosion and cloud. It is marketed as a target designator that is useful for persons who are firing at long ranges. For such a use, a long-range rifle shooter sets up targets and retreats to a distant firing position. The shooter does not need to walk down-range to see if the target has been hit, as the Tannerite will detonate and serve as a highly-visible indicator. Tannerite is also used for dramatic effect to provide explosions in weaponry demonstrations or other events. Ordinarily, firing rifle-caliber ammunition will not produce much more than a shattered target or hole (and the sound of the firing) when shot at a target. Using exploding targets can provide movie-like experiences such as exploding cars. The manufacturer recommends using no more than of the mixed composition at once, for safety reasons, although this guideline is not always followed and the product can be readily purchased in larger amounts. It is sometimes sold by the pound, and demonstrations of the effects of using up to at a time have become popular as internet videos.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tannerite」の詳細全文を読む スポンサード リンク
