It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough. Especially for little studied explosives there may be divergent published values due to charge diameter issues.
Iron(III) oxide in a vial. Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry.
Rust scale forming and flaking off from a steel bar heated to its forging temperature of 1200°C. Rapid oxidation occurs when heated steel is exposed to air. Rust is a general name for a complex of oxides and hydroxides of iron, [4] which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of ...
Explosive velocities are always higher than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force produced is focused on a much smaller area, and the pressure is significantly intensified. This results in an explosive velocity that is higher than if the explosive had ...
The round includes a high explosive and incendiary component and can also defeat light armor (hence its multi-purpose designation). [1] The self-destruct feature engages at approximately 2,300 metres (7,500 ft) [2] and destroys the round, preventing it from falling back to earth and inflicting damage to the surrounding territory. The price per ...

Entered service estimated 1988. A new type of explosive-filling was applied, which improved focusing of the jet stream. Country of origin: Soviet Union; Round weight: 28.4 kg; Projectile dimension: 680 mm; Projectile weight: 18.4 kg; Muzzle velocity: 915 m/s; Penetration: 350mm to 400mm RHA at 60 degree tandem-charge
The year 2024 was one for the history books, and 538's visual journalists and reporters were hard at work explaining the data behind the news with visualizations and interactives. From 538’s ...
