Phase Composition of the Products of Combustion of Ferroaluminum Silicon in Nitrogen in the Presence of Fluorine Containing Additives

“…Usually, ammonium salts, which on decomposition form the additional nitriding agent NH 3 , are used. It is shown in [4] that ammonium fluoride and topaz concentrate make it possible to increase the degree of nitriding of ferrosilicon to 100%.…”
