Abstract:
An exothermic composition comprises a particulate readily oxidisable metal such as aluminium, magnesium or silicon and an organic fluorine-containing compound, and usually an oxidising agent for the readily oxidisable metal. The preferred organic fluorine-containing compound is polytetrafluoroethylene. The composition may also contain a binder, a particulate refractory material, refractory fibres and/or organic fibres.
