摘要: The formation of Si3N4, during the carbothermic reduction SiO2 in presence small Fe additions combined with nitridation is a complex process involving several solid-solid, gas-solid, gas-liquid-solid, and gas-gas reaction stages. catalytic action iron manifests itself an intermediate compound — carbosilicide. product FeSixCy isα-Si3N4, that silicon, β-Si3N4.
