Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement.

2025年3月28日 · Nothing says "celebration!" like the pyrotechnic displays brought to you courtesy of flash powder—the stuff that makes flares flare, fireworks explode, and other fun things that go BOOM. Flash powder is a rapidly-burning mixture of an oxidizer and a fuel—commonly potassium perchlorate and aluminum powder—and is guaranteed to light things up.

A photoflash bomb, or flash bomb, is explosive ordnance dropped by aircraft, usually military surveillance aircraft, designed to detonate above ground to create an extremely bright flash of light.

In 1975, federal regulations were passed to limit all consumer-grade fireworks available for general sale to the public in the United States to a maximum of 50 milligrams flash powder, down from a previous maximum of 200 milligrams.

2025年3月13日 · Explosive pest control devices (EPCDs) generally fall under ATF regulation because they contain regulated explosive materials, such as flash powder, black powder, and/or other pyrotechnic compositions. Some of these devices go by the generic terms “bird bombs”, “shell crackers”, “whistlers” or similar terms.

It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for flashes in photography. Different varieties of flash powder are made from different compositions; most common are potassium perchlorate and aluminium powder.

The term “Flash Powder” (FP) refers to a mixture of oxiders and metallic fuels that burn quickly and make a loud noise regardless of their confinement in pyrotechnic field. There are multiple forms of FP, but the main common consists of potassium perchlorate (70 wt%) (KClO 4) as oxidizer and aluminium (30 wt%) (Al) as fuel [1].

Flash powder is a pyrotechnic composition which is composed of an oxidizer and a metallic fuel. The deflagration of this composition is very fast and is often accompanied by a loud report, especially when it is compressed. Nowadays, it is often used in fireworks. Historically, it was used to create flashes in photography.
