The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, pyrophoric gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid. [6] Silane is of practical interest as a precursor to elemental silicon.
Due to its large surface area and high volume of contained hydrogen gas, dry, activated Raney nickel is a pyrophoric material that requires handling under an inert atmosphere. Raney nickel is typically supplied as a 50% slurry in water. Even after reaction, residual Raney nickel contains significant amounts of hydrogen gas and may spontaneously ...
The structure and bonding in Al 2 R 6 and diborane are analogous (R = alkyl). In Al 2 Me 6, the Al-C(terminal) and Al-C(bridging) distances are 1.97 and 2.14 Å, respectively.The Al center is tetrahedral. [5]

Triethylaluminium thickened with polyisobutylene is used as an incendiary weapon, as a pyrophoric alternative to napalm; e.g., in the M74 clip holding four rockets for the M202A1 launchers. [15] In this application it is known as TPA, for thickened pyrotechnic agent or thickened pyrophoric agent. The usual amount of the thickener is 6%.
The exact formula of Phos-Chek is not public knowledge but the company has said in previous filings that the product is 80% water, 14% fertiliser-type salts, 6% colouring agents and corrosion ...
The effect was discovered when a small amount of water was found to enhance the activity in the Ziegler–Natta system. MAO serves multiple functions in the activation process. First it alkylates the metal-chloride pre-catalyst species giving Ti/Zr-methyl intermediates.
