ONE STEP PROCESS FOR PRODUCTION OF MO METAL FROM MOS3/MOS2 USING MICROWAVE ASSISTED HYDROGEN PLASMA

摘要

The present invention relates to a process for the production of Mo metal from Mo03/MoS2 by reduction in a microwave assisted hydrogen plasma reactor. Mo03/MoS2 particles in the form of pellets are exposed to hydrogen plasma using hydrogen flow rate 100 - 500 seem under pressure 40-90 torr and power 1000-1500 watt. Availability of the high energy flux and plasma state conditions in the hydrogen plasma allow the reactions to be completed in very short duration. The process is environment friendly as the exhaust gas generated could be utilized. The XRD patterns of the end product indicate the formation of high purity metallic molybdenum. This process can also be adapted for other molybdenum compounds like ammonium dimolybdate etc.
