The fuel mixtures include N,N,N′,N′-tetramethylethylenediamine (TMEDA) mixed with 2-N,N-dimethylaminoethylazide (DMAZ), TMEDA mixed with tris(2-azidoethyl)amine (TAEA), and TMEDA mixed with one or more ...

Pyrophoric material

Patent Number: 8430982
Publication Date: 2013-04-30
Inventors: ; ; ; ;

A pyrophoric material comprises a pyrophoric metal coated onto a wire mesh substrate. Iron and nickel are the preferred metals and a steel wire mesh is suitable. A process for making the pyrophoric material involves spraying an alloy of iron and/or nickel with aluminium onto a mesh using a high velocity oxy-fuel (HVOF) process following by leaching out at least a proportion of the aluminium by treatment with an alkaline solution. The product has application as a supported catalyst or as ...
