METHOD FOR REDUCING MOO3 AND PRODUCING LOW OXYGEN CONTENT MOLYBDENUM POWDER

摘要

PURPOSE: A method for reducing MoO_3(molybdenum trioxide) and manufacturing low-oxygen content molybdenum is provided to manufacture the MoO_3 to metal molybdenum power with 5 micrometers or less of particle size and low oxygen content. CONSTITUTION: A method for reducing MoO_3 and manufacturing low-oxygen content molybdenum is as follows: a step of putting a first reducing agent and the MoO_3 into a micro sieve positioned above a bracket(ST110); a step of putting a second reducing agent into the bracket positioned under the micro sieve; a step of a coupling a cover and a body; and a step of reducing the MoO_3 by increasing the temperature of the body.
