The nitriding of titanium–magnesium production waste containing chlorine was studied using X-ray, IR, EPR, and EPMA techniques as well as chemical and mass spectrometry analyses. It was established that the high-dispersion system, consisting mainly of silicon nitride and oxinitride, formed in the temperature range of 1273–1673 K. The complex defective structure of initial silicon particles and their size determine the mechanism of nitriding and phase composition of the product formed. The base of this mechanism is the formation of free Si— and Si— bonds. |
