Filtration Combustion Modes of Ferrosilicon in Nitrogen

The combustion of ferrosilicon in nitrogen is carried out in the self-oscillating mode but not in the stationary one. At the same time, harmonic oscillations are transformed into relaxation ones which consist of alternating flashes and depression. Propagation of a combustion wave is carried out as follows a bright flash is observed after the initiation of the reaction and then intensity of the flush gradually decreases and eventually ceases. Then, at some distance downward from 

the unstable (self-oscillating) combustion of ferrosilicon in nitrogen is accompanied by a low nitriding degree of combustion products and leads to their chemical and phase inhomogeneity. SHS process control is required to achieve the phase and chemical homogeneity of SHS products and the maximum (m = 1)
