Carbothermic Reduction of Mechanically Activated MoO3 to Synthesize Nano-Crystalline Metallic Mo

Article Preview

Abstract:

In this work, the synthesis of nano-crystalline molybdenum via mechanical activation and subsequent heat treatment using graphite as the reducing agent has been studied. XRD analysis showed that in a 50 hours milled sample, the first step of the reduction took place and MoO3 reduced to nano-crystalline MoO2 with a mean crystallite size of 34 nm. The resultant MoO2 converted to molybdenum when the 20 hours milled sample was heat treated at 1000 °C for 1 hour. FESEM images confirmed the formation of uniform particles of molybdenum after heat treatment.
