Plasma spraying methods of forming exoergic structures and coatings, as well as exoergic structures produced by such methods, are provided. The methods include the plasma spraying of reactive exoergic materials that are capable of sustaining a combustion synthesis reaction onto a flat substrate or into molds of arbitrary shape and igniting said plasma sprayed materials, either under an inert gas pressure or not, to form refractory materials of varying densities and of varying shapes.

A method of producing combustion synthesis products which comprises: (a) introducing an oxygen-free plasma-forming gas into a plasma spray; (b) introducing reactive exoergic materials capable of sustaining a combustion synthesis reaction in finely divided particulate form into said plasma spray directed toward, but not impinging on, a substrate; (c) melting, without chemically reacting, said exoergic materials in the plasma; (d) impinging said molten reactive exoergic material on said substrate; and (e) igniting said impinged exoergic materials.
