Abstract

The effects of iron-containing compounds on Si2N2O production during burning in N2 of an Si + SiO2 mixture were studied. It was established that the phase composition and morphology of the crystalline combustion products depended on the iron-containing compound. Si2N2O powder without impurity phases was obtained in the presence of FeCl3·6H2O and formed polycrystalline fibers consisting of ultrafine crystals.
