Mo Powders Fabricated from MoO3 with Hydrogen Gas |
| 초록 |
We studied the effect of temperature and reaction time by investigating the various temperatures and reaction times in the reduction of molybdenum oxide (MoO3) to molybdenum (Mo) powder in hydrogen gas. We also studied the effect of the reaction of reduction according to the various hydrogen gas flow rates. We surveyed the reduction from molybdenum oxide to molybdenum powder in hydrogen gas and checked two temperature ranges, one from 400℃ to 600℃ and the other from 700℃ to 900℃. We found that the reaction ratio of molybdenum oxide increased with an increasing temperature and also increased with an increasing reaction time, but hydrogen gas did not influence the reduction ratio of molybdenum oxide. We examined molybdenum powders fabricated by ball milling for two hours, using with X-ray diffraction (XRD) and a scanning electron microscopy (SEM) |
