Summary:Title screen
The results are presented from experimental studies to determine the effect the type of inert gas (helium, nitrogen, or argon) used in a mixture with oxygen as the gaseous medium of a reactor chamber has on the product of plasma dynamic synthesis in an iron-oxygen system. X-ray diffractometry and scanning electron microscopy are used to establish that the synthesized materials were ultrafine powders consisting mainly of magnetite Fe3O4 with small inclusions of hematite α-Fe2O3, wustite FeO, and iron Fe. It is found experimentally that the content of magnetite in the product can be as high as 85 wt % during plasma dynamic synthesis in mixtures of N2/O2 and He/O2, resulting in the highest specific saturation magnetization (up to 78.3 emu/g).
