Abstract Scope |
Commercial production of carbide materials is often associated with high energy costs due to the high temperatures and long milling times required to produce a powder carbide product. A process for synthesizing Mo2C was developed to reduce carburization temperatures and product particle size. Precursor material, produced by adsorbing molybdate anions onto activated carbon, was carburized under a reducing gas atmosphere to produce Mo2C at temperatures below 800°C. Molybdenum adsorption was measured using inductively coupled plasma spectroscopy, and carburization products were characterized using X-ray diffraction and scanning electron microscopy. Response surface analyses were used to mathematically model the adsorption and carburization processes and to determine optimal parameters for Mo-loading and Mo2C synthesis. The effects of temperature, time, pH, and initial Mo concentration were used to model adsorption behavior while the carburization process was modelled using the effects of temperature, reaction time, and reducing gas atmosphere on the synthesis of Mo2C. |
