Impact of ammonium acetate and ferric chloride additives on the SHS of polycrystalline silicon nitride fibers in nitrogen gas was investigated by XRD, SEM, and EDS. Our results suggest that the metallic drops formed in reactions of gaseous СО, SiО, and Si with Fe on the surface of the Fe–Si–С globules are capable of initiating the growth of 1D nanocrystals by the VLS–root mechanism.
