Reaction pathway in the MoO3+Mg+C reactive mixtures

Microwave-assisted synthesis of carbon-supported carbides catalysts for hydrous hydrazine decomposition

“…This finding and a significant decrease in the surface area of the product allowed us to hypothesize that MoO 3 vapor infiltrates into the porous carbon nanoparticles, and MoO 2 grows inside the pores via reaction 3 (see Figure 6). It was also shown previously that MoO 2 further reduces to molybdenum followed by formation of Mo 2 C at 650-900 o C [27]. In our study, the intermediate Mo phase has not been observed during microwave-assisted synthesis (Figure 1).…”

“…Earlier works [26], [27] suggest that carbon reduces MoO 3 at this temperatures by the following reaction: 2MoO 3(vapor) + C (s) = 2MoO 2(s) + CO 2(g)…”

Enhanced Electrochemical Performance of Heterogeneous Si/MoSi2 Anodes Prepared by a Magnesiothermic Reduction

“…Based on the previous measurements, it is reasonable to speculate that the formation of Si/MoSi 2 can be described as follows: (1) SiO 2 is reduced to Si by the magnesiothermic reduction; (2) When temperature rise to the melting point of magnesium, MoO 3 would be reduced by magnesium directly; 37 (3) Local heat accumulation facilitate the formation of MoSi 2 .…”

An investigation on aluminothermic reduction of MoO3 in domestic microwave oven

“…For separation of molybdenum metal from zinc oxide or magnesium oxide, HCl leaching can be used [15]. Manukyan et al reported self-sustaining reduction and reaction pathway in a MoO3+Mg+C mixtures that may yield molybdenum or molybdenum carbide, depending on the process conditions [16][17]. In the previous works, the reduction of molybdenum trioxide by aluminum doesn't have any attention due to formation of aluminum oxide that has not solubility by HCl leaching [14].…”
