<p>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 either an ignition medium or as a flare material in military countermeasures in which applications it is capable of burning at a high temperature.</p>
