The mechanism of copper (II) oxide and molybdenum (VI) oxide co-reduction by Mg + C mixture was investigated at non-isothermal conditions by carrying out simultaneous differential thermal (DTA) and thermogravimetric (TG) analyses combined with X-ray

In this work the reduction mechanisms of molybdenum oxide by single (Mg, Zn, C) and complex (Mg/C, Mg/Zn) reducers are reported. It is revealed that in the case of Mg and Zn the reduction undergoes before Mg/Zn melting, i.e. by solid-state mechanism.

In this work the reaction mechanism in the WO3–Mg/C systems and ammonium paratungstate (APT)–Mg/C systems are studied. As reducer magnesium, carbon or combinations of both are explored. It is shown that in the WO3–Mg system the reduction underg
