A pyrophoric material comprises a pyrophoric metal coated onto a wire mesh substrate.
The present invention provides a method for preventing and extinguishing fire, the method for preventing and extinguishing fire being effective against fire caused by a pyrophoric material and a water prohibitive substance.
The essence of the method is the use of pyrophorous metal powder and water-soluble polymeric binders when preparing the composition.
In an exemplary embodiment of the invention, a non-rotatable pyrophoric flint (40) is utilized which illustratively includes a body having a non-circular cross section.
The hardened steel striker facilitating the friction process against the pyrophoric element to discharge the ignited particles is self-contained within the device.
The pyrophorous metal powder of aluminum, magnesium, aluminum-magnesium alloy can be used as a fuel and a solution of polyethylene oxide in dioxane or methanol can be used as a binder.
This invention relates to a self-contained fire-starting tool that can be manually operated by one hand, producing a high volume of extremely hot sparks of ignited particles from a pyrophoric element.
The apparatus and method of the invention are preferably used for the encapsulation of radioactive waste materials, typically comprising uranium and/or its compounds, and avoid the formation of pyrophoric uranium hydride.
The reaction of the pyrophoric payload with air creates a signal that can be observed from a distance, thereby marking the landing or impact site of the projectile after it has been fired from a weapon.
