Tannerite is the brand name of a binary explosive, made from ammonium nitrate (oxidizer) and aluminum powder (fuel), that is supplied as two separate powders that are mixed and shaken to produce an explosive.
Although both have NH4NO3 and aluminium powder as their main ingredients, the main difference between Ammonal and Tannerite is that the former also has 2.4% charcoal in its composition, while the latter does not, though some formulations may also have 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydride, as well as a few percentages of ammonium perchlorate in the ammonium nitrate.
Contents
Composition
Tannerite generally consists of 95% ammonium nitrate and 5% aluminium powder by weight.
Other formulations specify that the fuel part consisting of 90% 600-mesh dark flake aluminum powder, combined with the catalyst which is a mixture of 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydride, while the oxidizer being 85% 200-mesh ammonium nitrate and 15% ammonium perchlorate.
Properties
Tannerite is a white-gray granular material. It is stable when subjected to forces less severe than a high-velocity bullet impact, such as being dropped, a hammer blow, or impact from a low-velocity bullet or even shotgun blast. It's not flammable – an explosion cannot be created by a burning fuse or electric arch.
Availability
Tannerite is freely available in the US, although restrictions exist on transport, storage and use.
Projects
- Explosions in weaponry demonstrations
Safety
Handling and storage
When the components are kept separate, Tannerite is stable and safe to handle.
Tannerite as separate components should be kept in safe places.
Legality
In US, the sale of Tannerite in the form of separate components is legal, though the legislation on its use is murky. Binary explosives are not classified as explosive materials, when kept as separate components. However, the moment they are mixed, the resulting mixture is considered explosive material.
The regulations on binary explosives state that:
- "Persons manufacturing explosives for their own personal, non-business use only (e.g., personal target practice) are not required to have a Federal explosives license or permit. However, individuals or companies must obtain a Federal explosives manufacturing license if they intend to engage in the business of manufacturing explosives for sale or distribution, or for their own business use."[1]
Some states place restrictions on where it can be used. As it is sold as two separate powders, it can be generally transported and sold without the legal restrictions that would otherwise apply to explosives.
Disposal
Safely detonating it in a special area. As it does not explode when burned, it can also be neutralized via controlled incineration.
