Effect of Iron Oxalate Additions on the Phase Composition of Combustion Products of Silicon–Carbon Mixtures in Nitrogen

Resumo

We have examined the effect of iron oxalate (Fe₂(C₂O₄)₃ · 5H₂O) additions on the phase composition of combustion products of silicon–carbon mixtures in nitrogen. The phase composition of the combustion products has been determined as a function of starting-mixture composition and nitrogen pressure. We have investigated the microstructure of the synthesized powders. The addition of SiO₂ to the starting mixture has been shown to increase the percentage of Si₂N₂O in the combustion products.
