Reduction of MoO2 to Metallic Molybdenum via Carburization and Thermal Process
A metallic molybdenum is formed by a two-stage process that was carburized MoO2 with carbon monoxide followed by heat treatment. XRD techniques were employed to identify the phase’s changes in the sample. It was found that by the present of carbon monoxide during carburization process until 900 °C, Mo2C is formed first, compared to metallic molybdenum, due to the high thermodynamic barrier for formation of metallic molybdenum. In the second stage, Mo2C further reacts with the remaining MoO2 at 900 °C to produce metallic molybdenum.
