<div>A '''pyrolant''' (from Greek ''pyros'', fire) is an energetic material that generates hot [[flames]] upon [[combustion]]. Pyrolants are metal-based [[pyrotechnic composition]]s containing virtually any oxidizer.<br />
The term was originally coined by Kuwahara in 1992,<ref>T. Kuwahara, T. Ochiachi, Burning Rate of Mg/TF Pyrolants, ''Proceedings of the 18th Int. Pyrotechnics Seminar'', '''1992''', p. 539.</ref> in a paper on [[magnesium/Teflon/Viton]], to distinguish between compositions that serve as propellants and those yielding hot flames which are not necessarily suitable for propellant purposes. <br />
<br />
The word ''[[thermite]]'' also refers to metal-oxidizer mixtures, and is used interchangeably with, and more commonly than, "pyrolant". <br />
<br />
A similar common term is ''[[propellant]]'', which describes either a homogeneous or composite material that generates thrust upon combustion, but which may contain fuels instead of or in addition to the metals contained in [[thermite]]s.<br />
<br />
Metal-based pyrotechnic compositions, that is to say [[thermite]]s or pyrolants, are generally characterized by high combustion temperatures (> 2000 K) and high amounts of condensed reaction products at equilibrium conditions such as metal [[oxide]]s, [[fluoride]]s and [[soot]].<br />
