Synthesis of magnetite powder from the mixture consisting of siderite
If the amount of siderite in the mixture decreases, the content of hematite increases (Fig. 11 a). The reason for this is the lack of a reductant (carbon monoxide) produced from the carbonyl group of siderite. An increase in siderite content from 50% to 80% leads to wüstite formation in addition to magnetite (Fig. 11 c).
