Output (English): Metallic iron oxide is a carbothermal reduction of starting materials such as magnesium oxide, containing a large amount of oxide, iron Fe, Si, in Ca, and aluminum to aluminum and / or aluminum-based materials such as pressure, pressure and atmospheric pressure. The metal sheath is removed from the shear and the metal sheath and the oxide is emitted to form a condensate. As the SiO2 is used as SiO2, the first condenser forms the second condenser, you are converted to carbide to SiC and the alloy is bonded to SiC. Si and iron Fe in the reaction mixture. Thus, the starting materials can be processed by a method whereby their component is converted into oxide oxide in reaction, while the other components are converted into carbide to form carbon monoxide. SiC and Si alloy and iron Fe, gold Au and other siderophile elements can be made of Si alloys and Fe.
