According to my knowledge, The process of making Molybdenum oxide from pure Molybdenum metal involves oxidation of Molybdenum metal in the presence of an oxidizing agent.
Materials required;
Pure Molybdenum metal (powder form)
Oxidizing agent (e.g. hydrogen peroxide, nitric acid, or oxygen gas)
Mortar and pestle
Crucible
Furnace or hot plate
Gloves and safety goggles
Procedure;
Grind the Molybdenum metal into a fine powder using a mortar and pestle.
Weigh the desired amount of Molybdenum powder for the experiment.
Transfer the Molybdenum powder into a crucible.
Place the crucible into a furnace or hot plate.
Heat the crucible to 600-700°C in air for several hours. This will oxidize the Molybdenum metal into Molybdenum oxide. The exact time required will depend on the amount of Molybdenum powder and the temperature used.
Reaction equation 2Mo(s) + 3 O2(g) ==> 2MoO3(s)
Remove the crucible from the furnace or hot plate and allow it to cool to room temperature.
Weigh the Molybdenum oxide obtained.
Safety Measurements;
The oxidation of Molybdenum metal can generate significant heat and gas, and should be performed with care in a well-ventilated area while wearing protective gloves and goggles. The exact details of the process may vary depending on the specific oxidizing agent used.
