first time by high-resolutionneutrondiffraction between 3.5 and 300 K using well-crystalline samples. Although the neutron-diffraction quality is perfectly able to detect even the magnetic states of the impurities MnO and γ-Mn, there is no sign of a magnetic ordering for Mn3C down to 3.5 K. Hence, it is justified to characterize Mn3C as paramagnetic at the time being.
Cycle” was studied in order to produce new fuel gas. This process consists of four steps; (i) carbide production from Mn2O3 and solid carbon sources, (ii) fuel gas production by means of hydrolysis of the carbide, (iii) spontaneous oxidation of Mn(OH)2 with air to Mn2O3, and (iv) regeneration of the carbide from Mn2O3 and new carbon sources. In this process, manganese is used as a recyclable medium
